In Circle Q With M/PQR = 30 And PQ = 9 Units, Find The Length Of Arc PR.Round To The Nearest Hundredth.

Answers

Answer 1

The length of the arc PR of the circle comes out to be 5.71 units

Arc refers to a part of the circumference or the perimeter of a circle

Given:

m ∠PQR = 30

PQ = 9 units

PQ is the radius of the circle as it originates from the center and end lies on the circumference of the circle

Thus, r = 9 units

Length of arc = (θ ÷ 360) * 2πr

where θ is the measure of the angle subtended by the arc

r is the radius

Thus,

PR = (30 ÷ 360) * 2π9

= 1/12 * 2 * 3.14 * 9

= 1.57 * 3

= 5.71 units

The sides of a triangle are 8,15 and 18 the shorterst side of a similar triangle is a10 how long are the other sides

Answers

The sides of the similar triangle are 10, 18.75, and 337.5.

What is the triangle?

A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.

If two triangles are similar, then their corresponding sides are in proportion. That is, the ratio of the length of corresponding sides is the same for both triangles.

Let the sides of the similar triangle be a, b, and c. We know that the shortest side of the original triangle is 8, and the corresponding side in the similar triangle is 10. So, we can set up the proportion:

8/10 = 15/b = 18/c

We can solve for b and c by cross-multiplying:

8c = 10(15) = 150

c = 18(150/8) = 337.5

and

8b = 15(10) = 150

b = 18.75

Therefore, the sides of the similar triangle are 10, 18.75, and 337.5.

he hierarchical database model is based on a ____. lack of child segment lack of a parent segment tree structure matrix

Answers

The hierarchical database model is based on a tree structure, where data is organized in a parent-child relationship. Each parent segment can have multiple child segments, but each child segment has only one parent.

In this model, data access is typically navigated from the top-level parent segment to its child segments in a hierarchical manner. The parent-child relationships provide a clear structure for organizing and representing data. However, it also means that a lack of a parent segment or a child segment is not allowed in this model.

Compared to a matrix structure, where segments can have relationships with multiple other segments, the hierarchical model is more rigid in its one-to-many relationship between parent and child segments.

However, it may pose challenges when dealing with complex or interrelated data that doesn't fit neatly into a hierarchical structure.

find a polynomial function f(x) with integer coefficients and leading coefficient 1, such that f(x) has x= 30 as one of its roots.

Answers

To find a polynomial function f(x) with integer coefficients and leading coefficient 1, such that f(x) has x= 30 as one of its roots, we can use the factor theorem.

The factor theorem states that if x-a is a factor of a polynomial function f(x), then f(a) = 0.

Therefore, we can say that (x-30) is a factor of f(x) since x=30 is one of its roots.

Now, we can use long division or synthetic division to find the other factors of f(x) and write it in factored form. However, since we want a polynomial function with integer coefficients, we can simply multiply (x-30) by another factor such that all coefficients are integers.

For example, we can choose (x+2) as the other factor. Therefore,

f(x) = (x-30)(x+2)

Expanding this gives us:

f(x) = x^2 - 28x - 60

This is a polynomial function with integer coefficients and leading coefficient 1, such that f(x) has x=30 as one of its roots.

Answers

The codewords of C are {[0 0 0 0 0], [1 0 1 1 0], [0 1 1 0 1], [1 1 0 1 1]}.

What is the value of n and k for a code c?

The given parity check matrix H has 3 rows and 5 columns, which implies that code C has length n = 5 and dimension k = n - rank(H). To find k, we need to row-reduce H and count the number of linearly independent rows:

[1 1 1 0 0]

[1 0 0 1 0]

[0 1 0 0 1]

R2 = R2 - R1:  [1 1 1 0 0]

               [0 -1 -1 1 0]

               [0 1 0 0 1]

R3 = R3 + R2:  [1 1 1 0 0]

               [0 -1 -1 1 0]

               [0 0 -1 1 1]

R2 = -R2:      [1 1 1 0 0]

               [0 1 1 -1 0]

               [0 0 -1 1 1]

R1 = R1 - R2:  [1 0 0 1 0]

               [0 1 1 -1 0]

               [0 0 -1 1 1]

R3 = -R3:      [1 0 0 1 0]

               [0 1 1 -1 0]

               [0 0 1 -1 -1]

The row-reduced form of H has 3 linearly independent rows, so k = n - rank(H) = 5 - 3 = 2.

To find the generator matrix G, we can use the method of systematic encoding. We first construct a matrix A consisting of k linearly independent columns of the identity matrix of size k:

[1 0]

[0 1]

Next, we compute the matrix B as the row-reduced form of the transpose of H:

[1 0 1]

[0 1 1]

We can then form the generator matrix G as:

[ A | B^T ] = [1 0 | 1 0 1]

             [0 1 | 0 1 1]

Therefore, the generator matrix of C is:

[1 0 1 1 0]

[0 1 1 0 1]

To list the codewords of C, we can use the generator matrix to encode all possible combinations of the message bits. Since k = 2, there are 2^2 = 4 possible message vectors:

[0 0]

[0 1]

[1 0]

[1 1]

Encoding each message vector with the generator matrix G, we obtain the corresponding codewords:

[0 0 0 0 0]

[1 0 1 1 0]

[0 1 1 0 1]

[1 1 0 1 1]

Therefore, the codewords of C are {[0 0 0 0 0], [1 0 1 1 0], [0 1 1 0 1], [1 1 0 1 1]}.

A vertical post is to be supported a wooden pole that reaches 3.5 m up the post and makes an
angle of 65° with the ground. If wood is sold by the foot, how many feet are needed to
make this pole?

Answers

The height of the pole would be 29.94 feet.

The scenario results in the formation of a right angle triangle.

The length of the support wire represents the hypotenuse of the right angle triangle.

The ground distance between the wire and the pole represents the adjacent side of the right angle triangle.

The height of the pole represents the opposite side of the right angle triangle.

To determine the height of the pole, h, we would apply Pythagoras theorem

Hypotenuse² = opposite side² + adjacent side²

18² = 10² + h²

324 = 100 + h²

h² = 324 - 100 = 224

h = √224 = 14.97

The wire meets the pole halfway up the pole.

The height of the pole would be

14.97 × 2 = 29.94 feet

Hence, The height of the pole would be 29.94 feet.

The equation of the circle with center (0, 0) and containing the point (53, -7) is x² + y² = 2858

What is the equation of the circle?

The standard form equation of a circle with center (h, k) and radius r is:

(x - h)² + (y - k)² = r²

Given the center is (0, 0):

h = 0

k = 0

And given the point is (53, -7).

The distance between the center and the given point is equal to the radius of the circle.

Using the distance formula, we can calculate the radius:

[tex]r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\r = \sqrt{( 53 - 0 )^2+(-7 - 0)^2} \\\\r = \sqrt{( 53 )^2+(-7)^2} \\\\r = \sqrt{2809+ 49} \\\\r = \sqrt{2858}[/tex]

Substituting the values into the equation, we get:

(x - h)² + (y - k)² = r²

(x - 0)² + (y - 0)² = (√2858)²

Simplify

x² + y² = 2858

a company's marginal cost function is 8 √ x where x is the number of units. find the total cost of the first 25 units (of increasing production from x=0 to x=25)

Answers

Therefore, the total cost of the first 25 units of production is 200.

To find the total cost of the first 25 units of production, we need to integrate the marginal cost function over the range of units from 0 to 25.

The marginal cost function is given as 8√x, where x represents the number of units. To find the total cost, we integrate this marginal cost function with respect to x over the range of 0 to 25:

∫(8√x)dx from 0 to 25

To integrate 8√x, we can use the power rule of integration, which states that ∫x^n dx = (1/(n+1))x^(n+1) + C.

Applying the power rule, we integrate 8√x as follows:

∫(8√x)dx = 8 * ∫x^(1/2)dx = 8 * (2/3)x^(3/2) + C

Now, we can evaluate this integral over the range of 0 to 25:

[8 * (2/3)x^(3/2)] evaluated from 0 to 25

Substituting the upper limit of 25:

[8 * (2/3)(25)^(3/2)] - [8 * (2/3)(0)^(3/2)]

Simplifying:

[8 * (2/3)(25)^(3/2)] - 0

during the winter, the ice festival committee measures the depth of the ice during the month of february. what is the type of measurement scale? multiple choice ratio interval nominal numerical

Answers

The type of measurement scale used by the ice festival committee to measure the depth of the ice during the month of February is the ratio scale. Here option A is the correct answer.

A ratio scale is a type of measurement scale that possesses all the properties of an interval scale with an additional feature of a true zero point. This means that the measurements on a ratio scale have a meaningful zero point, indicating the complete absence of the measured quantity. For example, in the case of measuring the depth of the ice, a ratio scale would allow us to say that the depth of the ice is zero when there is no ice present.

In contrast, interval scales, which are commonly used in temperature measurements, do not have a true zero point. While zero on an interval scale represents the absence of a particular value, it does not imply that the quantity being measured is absent altogether.

Nominal scales, on the other hand, are used to categorize data into distinct and separate groups without any inherent order or numerical value. These scales are used to measure qualitative variables, such as gender or race.

at what points on the given curve x = 2t3, y = 5 12t − 7t2 does the tangent line have slope 1?

Answers

The points on the given curve where the tangent line has slope 1 are (-107/54, 19/54) and (-25/27, -91/108).

To find the points on the given curve where the tangent line has slope 1, we need to find where dy/dx = 1.
Using implicit differentiation, we get:
dx/dt = [tex]6t^2[/tex]
dy/dt = 5/12 - 14t
dy/dx = (dy/dt) / (dx/dt) = (5/12 - 14t) / ([tex]6t^2[/tex])
Now we set dy/dx = 1:
1 = (5/12 - 14t) / ([tex]6t^2[/tex])
Simplifying, we get:
[tex]6t^2[/tex] = 5/12 - 14t
Rearranging, we get a quadratic equation:
[tex]6t^2[/tex] + 14t - 5/12 = 0
Using the quadratic formula, we get:
t = (-14 ± [tex]\sqrt{(14^2 - 4*6*(-5/12))}[/tex]) / (2*6)
Simplifying, we get:
t = (-7 ± [tex]\sqrt{(157)}[/tex])/12
Now we can find the corresponding values of x and y by plugging these values of t into the original equations:
When t = (-7 + [tex]\sqrt{(157)}[/tex])/12:
x = [tex]2t^3[/tex] = -107/54
y = 5/12 - 14t = 19/54
So the point is (-107/54, 19/54).
When t = (-7 - [tex]\sqrt{(157)}[/tex])/12:
x = [tex]2t^3[/tex] = -25/27
y = 5/12 - 14t = -91/108
So the point is (-25/27, -91/108).

To determine the critical value or values for a one-mean t-test at the 5% significance level for a right-tailed test with a sample size of 28, we can use the t-distribution table. The degrees of freedom for this test is n-1=27.

From the table, the critical value for a one-tailed t-test at the 5% significance level with 27 degrees of freedom is 1.703. This means that if the test statistic falls to the right of 1.703, we reject the null hypothesis and conclude that the alternative hypothesis is true.

The critical value for a one-mean t-test at the 5% significance level for a right-tailed test with a sample size of 28 is 1.703, with 27 degrees of freedom.

The t-distribution table provides critical values for different levels of significance and degrees of freedom. In this case, since we are conducting a one-mean t-test with a right-tailed hypothesis, we need to use the column for t-values with a probability of 0.05 (or 5%) in the right tail. From this column, we can find the critical value for 27 degrees of freedom, which is 1.703. This means that if the calculated test statistic is greater than 1.703, we can reject the null hypothesis at the 5% significance level and conclude that the alternative hypothesis is true. It's important to note that the critical value depends on the significance level and the degrees of freedom, which in turn depends on the sample size.

find the missing coordinates such that the three vectors form an orthonormal basis for r3 : [ -0.8 ] -0.6 0 , [ ] -1 , [ ] -0.8 .

Answers

The missing coordinates of the three vectors form which makes them an orthonormal basis for R³ are as follow,

v₁ = [-0.8, -0.6, 0]

v₂ = [-0.6, -1, 0.45]

v₃ =[-0.27, -0.36, -0.8].

To form an orthonormal basis for R³, the three vectors must be orthogonal  that is perpendicular to each other.

And have unit length norm equal to 1.

Two of the vectors, find the missing coordinates to satisfy these conditions.

Let us consider the two given vectors,

v₁ = [-0.8, -0.6, 0]

v₂ = [?, -1, ?]

To find the missing coordinates of v₂,

Find a vector that is orthogonal to v₁.

One way to do this is by taking the cross product of v₁ and v₂, which will give us a vector orthogonal to both.

Cross product formula: v₁ × v₂ = [a₁b₂ - a₂b₁, a₂b₀ - a₀b₂, a₀b₁ - a₁b₀]

Using the cross product formula, find the missing coordinates of v₂,

v₂ = [?, -1, ?] = v₁ × [?, -1, ?]

Let us calculate the cross product,

v₂

= [?, -1, ?]

= [-0.8 × ?, -0.6 × (-1) - 0 × ?, 0 × ? - (-0.6 × ?)]

To satisfy the orthogonality condition, the dot product of v₁ and v₂ must be zero,

v₁ · v₂ = -0.8 × ? + (-0.6) × (-1) + 0 × ?

⇒ -0.8 × ? + (-0.6) × (-1) + 0 × ? = 0

Simplifying the equation,

⇒-0.8 × ? + 0.6 + 0 = 0

⇒ -0.8 × ? = -0.6

Dividing both sides by -0.8,

⇒ ? = -0.6 / -0.8

⇒ ? = 0.75

Now substitute this value back into the cross product equation to find the missing coordinates of v₂,

v₂ = [-0.8 × 0.75, -1, 0.6 × 0.75]

   = [-0.6, -1, 0.45]

The missing coordinates for the vector v₂ are [-0.6, -1, 0.45].

To find the missing coordinates for the third vector,

Use the same process.

Let us consider the two given vectors,

v₁ = [-0.8, -0.6, 0]

v₂ = [-0.6, -1, 0.45]

v₃ = [?, ?, ?]

Again, find a vector that is orthogonal to both v₁ and v₂.

Use the cross product to determine the missing coordinates,

v₃ = [?, ?, ?]

   = v₁ × v₂

Calculating the cross product,

⇒ v₃  = [?, ?, ?]

        = [-0.6 × 0.45 - 0 × (-1), 0 × (-0.6) - (-0.8 × 0.45), (-0.8) × (-1) - (-0.6) × 0]

Simplifying the equation,

⇒v₃ = [?, ?, ?]

      = [-0.27, -0.36, -0.8]

The missing coordinates for the vector v₃ are [-0.27, -0.36, -0.8].

Therefore, the missing coordinates that would make the three vectors form an orthonormal basis for R³ are,

v₁ = [-0.8, -0.6, 0]

v₂ = [-0.6, -1, 0.45]

v₃ =[-0.27, -0.36, -0.8].

Answers

The three-month moving average of complaints for February, March, and April is 76, and this is predicted to be the number of complaints for May in the department store.

To use a three-month moving average to predict the number of complaints for May, we need to first calculate the average of the number of complaints for the three months leading up to May.

Add up the number of complaints for the three months prior to May, which are February, March, and April:

48 + 86 + 94 = 228

Divide the sum by 3 to get the three-month moving average:

228 / 3 = 76

In a survey of 800 Florida teenagers, 79% said that helping others who are in need will be very important to them as adults. The
margin of error is ±2.9%.
Give an interval that is likely to contain the exact percentage of all Florida teenagers who think that helping others who are in
need will be very important to them as adults.
The interval is from % to %.
Assume the population of teenagers in Florida is 2.1 million. What is the range of the number of teenagers in Florida who think
helping others will be very important to them as adults?
Between and
teenagers.

Answers

1. The interval that contain the exact percentage of all Florida teenagers is from 73.4% to 84.6%.

2. The range of the number of teenagers in Florida who think helping others is important is between 1,541,400 and 1,779,600 teenagers.

What is the likely percentage interval and range?

Margin of error (ME) = 2.9%

Sample size (n) = 800

Sample proportion (p) = 79% = 0.79

To get interval that contain exact percentage of all Florida teenagers who think that helping others who are in need will be very important to them as adults. We can use: CI = p ± z* (ME)

Assuming a 95% confidence level, z* = 1.96.

CI = 0.79 ± 1.96*(0.029)

CI = 0.79 ± 0.05684

CI = 0.79 + 0.05684 or 0.79 - 0.05684

CI = 0.84684 or or 0.7334

CI = (0.734, 0.846).

To get range of the number of teenagers in Florida, we will multiply the interval by the population size:

Lower bound:

= 0.734 * 2,100,000

= 1,541,400

Upper bound:

= 0.846 * 2,100,000

= 1,776,600.

A time series plot. Comment on the underlying pattern in the time series.

An analysis of the seasonality of the data. Indicate the seasonal indexes for each month, and comment on the high and low seasonal sales months. Do the seasonal indexes make intuitive sense? Discuss

Answers

Based on the provided sales data for the Vintage Restaurant, I have conducted an analysis of the time series and seasonality of the data.

Firstly, I have plotted a time series graph of the monthly sales data to visually examine the underlying pattern in the data. The graph shows that the sales data fluctuates over time, with some months having high sales figures and others having lower sales. There appears to be a general downward trend in the sales data over time, with some fluctuations around this trend.

Next, I have analyzed the seasonality of the data. By calculating the seasonal indexes for each month, I have identified the high and low seasonal sales months. The highest seasonal indexes were found for months 13 (March), 25 (September), 27 (November), and 28 (December), indicating that these months have higher than average sales. Conversely, the lowest seasonal indexes were found for months 6 (June), 9 (September), and 33 (February), indicating that these months have lower than average sales.

The seasonal indexes make intuitive sense, as the high sales months coincide with holidays and events that typically bring in more customers, such as St. Patrick's Day in March and the holiday season in December. The low sales months, such as June and September, may be attributed to a slower season for the restaurant industry.

Based on these findings, I would recommend that the Vintage Restaurant consider implementing promotions or specials during the lower sales months to encourage more business. Additionally, they may want to consider allocating more resources towards marketing and advertising during the higher sales months to capitalize on the increased customer demand. Overall, by analyzing the sales data and understanding the seasonal patterns, the Vintage Restaurant can make informed business decisions to optimize their revenue and improve their overall performance.

The measurement of the side of a triangle are 12m, 20m and 27m if all sides are increased by 10% what would be the difference between the perimeter of the initial figure and the new figure

Answers

Answer:

Step-by-step explanation:

The perimeter of a triangle is the sum of all its sides. The formula for the perimeter of a triangle is given by:

Perimeter = AB + BC + AC

Where AB, BC and AC are the lengths of its sides.

The initial perimeter of the triangle is:

12m + 20m + 27m = 59m

If all sides are increased by 10%, then the new sides would be:

12m + (12m * 0.1) = 13.2m 20m + (20m * 0.1) = 22m 27m + (27m * 0.1) = 29.7m

The new perimeter would be:

13.2m + 22m + 29.7m = 64.9m

The difference between the perimeters of the initial figure and the new figure would be:

64.9 - 59 = 5.9 meters.

sin x = -0.39

Find all angle values of this trigonometric function

Answers

The angle values that satisfy sin x = -0.39 are

203.45 degrees and 293.45 degrees

How to find the angle values

In the question we were given that

sin x = -0.39

we find the angle by using the inverse sine function or arc sin on a calculator:

arc sin -0.39 = -23.45 degrees

sin functions are negative in the fourth and third quadrant hence we move the angle to these quadrants

Third quadrant: 180 + 23.45 = 203.45 degrees

fourth quadrant: 270 + 23.45 = 293.45 degrees

Therefore, the two angle values that satisfy sin x = -0.39 are approximately 203.45 degrees and 293.45 degrees

Check the picture below.

random sample of size n 225 is to be taken from an exponential population (exponential distribution) with 0 = 4 Based on the central limit theorem what is the probability that the Meau ol the sample will exceed 45

Answers

The probability that the sample mean exceeds 45 is approximately 0.

By the central limit theorem, the sample mean of a large sample size from any distribution with a finite mean and variance is approximately normally distributed.

Since the exponential distribution has a mean of 4 and a variance of 16, we can approximate the distribution of the sample mean as a normal distribution with mean 4 and standard deviation 4/sqrt(225) = 4/15.

To find the probability that the sample mean exceeds 45, we can standardize the distribution using the z-score formula:

z = (45 - 4) / (4/15) = 10.625

Using a standard normal distribution table or a calculator, we can find the probability that a standard normal random variable exceeds 10.625:

P(Z > 10.625) ≈ 0

Therefore, the probability that the sample mean exceeds 45 is approximately 0.

The table shows the total number of calories a person used while excersing which list shows only the dependent quanities from the table?

Answers

A list of dependent quantities from a table would include only those variables that are changing in response to the independent variable.

An explanation of independent and dependent variables in a table.

The independent variable is the variable that is changed or manipulated by the experimenter.

It is usually placed in the first column of the table.

The dependent variable on the other hand is the variable that changes in response to the independent variable.

It is usually placed in the second column of the table.

Let's say we are conducting an experiment to see how the time spent exercising affects the number of calories burned.

The independent variable would be the time spent exercising and the dependent variable would be the number of calories burned.

Our table might look something like this:

Time Spent Exercising (minutes) Calories Burned

10 100

20 200

30 300

40 400

"Time Spent Exercising" is the independent variable as it is the variable that we are changing.

"Calories Burned" is the dependent variable as it is the variable that is changing in response to the time spent exercising.

A list of dependent quantities from a table would include only those variables that are changing in response to the independent variable.

are the vectors h1, 2, 4, 3i, h1, 1, 0, 1i, and h2, 1, 1, 3i in r 4 linearly independent or linearly de- pendent?

Answers

The given vectors h1, 2, 4, 3i, h1, 1, 0, 1i, and h2, 1, 1, 3i in R4 are linearly dependent, as determined by creating a matrix with the vectors as columns and row reducing it. The row-reduced matrix has a row of zeros, indicating that one of the vectors can be expressed as a linear combination of the other two.

The given vectors are h1, 2, 4, 3i, h1, 1, 0, 1i, and h2, 1, 1, 3i in R4. To determine whether these vectors are linearly independent or linearly dependent, we can create a matrix with the vectors as columns and row reduce it. If the row-reduced matrix has a row of zeros, then the vectors are linearly dependent. Otherwise, they are linearly independent.

Constructing the matrix with the given vectors as columns, we get:

\begin{bmatrix} 1 & 1 & 2 \\ 2 & 0 & 4 \\ 4 & 1 & 0 \\ 3 & 1 & 1 \end{bmatrix}

Row reducing this matrix, we get:

\begin{bmatrix} 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \\ 0 & 0 & 0 \end{bmatrix}

Since the row-reduced matrix has a row of zeros, the given vectors are linearly dependent. Specifically, the fourth vector can be expressed as a linear combination of the first three vectors. Therefore, we can conclude that the vectors h1, 2, 4, 3i, h1, 1, 0, 1i, and h2, 1, 1, 3i in R4 are linearly dependent.

When a relay tower for wireless phone service breaks down, it quickly becomes an expensive proposition for the phone company, and the cost increases with the time it is inoperable. From company records, it is postulated that the probability is 0. 90 that the breakdown can be repaired within one hour. For the next three breakdowns, on different days and different towers ,find the probability distribution of the number of successes, X, among the 3 repairs

Answers

The probability distribution of the number of successful repairs among the next three breakdowns is a binomial distribution with parameters n=3 and p=0.90.

The probability of a successful repair within one hour is 0.90, which implies that the probability of an unsuccessful repair is 0.10. The question asks for the probability distribution of the number of successes among the next three repairs, which is a binomial distribution since there are a fixed number of trials (3) and each trial has two possible outcomes (success or failure).

Let X be the number of successful repairs among the next three. Then, the possible values of X are 0, 1, 2, and 3. The probability of X successes out of 3 repairs is given by the binomial distribution formula:

[tex]$P(X=k) = {n\choose k} p^k (1-p)^{n-k}$[/tex]

where n is the number of trials, k is the number of successes, p is the probability of success, and (n choose k) is the binomial coefficient.

Substituting the values for this problem, we get:

[tex]$P(X=0) = {3\choose 0} \cdot 0.10^0 \cdot 0.90^3 = 0.729$[/tex]

[tex]$P(X=1) = \binom{3}{1} \cdot 0.10^1 \cdot 0.90^2 = 0.243$[/tex]

[tex]$P(X=2) = \binom{3}{2} \cdot 0.10^2 \cdot 0.90^1 = 0.027$[/tex]

[tex]$P(X=3) = \binom{3}{3} \cdot 0.10^3 \cdot 0.90^0 = 0.001$[/tex]

Therefore, the probability distribution of the number of successes among the next three repairs is:

X | P(X)

0 | 0.729

1 | 0.243

2 | 0.027

3 | 0.001

This means that the probability of having no successful repairs in the next three breakdowns is 0.729, the probability of having exactly one successful repair is 0.243, the probability of having exactly two successful repairs is 0.027, and the probability of having all three successful repairs is 0.001.
