A statistical test conducted to determine whether to reject or not reject a hypothesized probability distribution for a population is known as the goodness of fit test.

Option C is the correct answer.

We have,

A goodness of fit test is conducted to determine whether a hypothesized probability distribution for a population adequately fits or matches the observed data.

It compares the observed data to the expected distribution specified by the hypothesis and assesses whether there is sufficient evidence to reject the hypothesis.

This test is commonly used when testing the fit of categorical data to a specified distribution, such as testing whether the observed data follows a specific discrete probability distribution

(e.g., Poisson, binomial, multinomial) or whether the observed data matches the expected proportions in different categories.

The goodness of fit test evaluates the degree of discrepancy between the observed and expected frequencies or proportions and provides a statistical measure, such as the chi-squared test statistic, to assess the level of agreement or disagreement between the observed data and the hypothesized distribution.

Therefore,

Surface area is the measure of the total area that the surface of a three-dimensional object occupies. It is the sum of the areas of all the faces or surfaces of the object.

According to the given information:

The surface area of a rectangular prism can be calculated by adding up the areas of all six faces. The formula for the surface area of a rectangular prism is:

Surface Area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the prism, respectively.

In this case, the length, width, and height of the rectangular prism are 14 inches, 8 inches, and 3 inches, respectively. Substituting these values into the formula, we get:

Surface Area = 2(14)(8) + 2(14)(3) + 2(8)(3)

= 224 + 84 + 48

= 356

Answer:

y = -4.3x + 23.8

Step-by-step explanation:

To find the equation for g(x), we need to first understand what it means for g(x) to be parallel to f(x). Two lines are parallel if they have the same slope, but different y-intercepts. The slope of f(x) is -4 3/10, which can be written as -43/10 in fraction form and -4.3 in decimal form. Therefore, the slope of g(x) is also -4.3.

Now we need to use the fact that g(x) passes through the point (6, -2) to find its y-intercept. We can use the point-slope form of a linear equation to do this: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

Plugging in our values, we get:

y - (-2) = (-4.3)(x - 6)

Simplify the left side

y + 2 = (-4.3)(x - 6)

Next, simplify the right side

y + 2 = -4.3x + 25.8

Subtracting 2 from both sides, we get:

y = -4.3x + 23.8

Therefore, the equation for g(x) is y = -4.3x + 23.8 in simplified slope-intercept form.

Julieta can travel 5.5 miles than Camila on one gallon of gas.

To find out how many miles more Julieta can travel than Camila on one gallon of gas, we need to compare their respective rates of miles per gallon.

According to the equation y = 38.8x, Camila can drive y miles for every x gallons of gas. Therefore, her rate of miles per gallon is:

y/x = 38.8

On the other hand, Julieta can drive 333 miles on 10 gallons of gas, so her rate of miles per gallon is:

333/10 = 33.3

To find out how many more miles per gallon Julieta can drive than Camila, we can subtract Camila's rate from Julieta's rate:

33.3 - 38.8 = -5.5

This means that Camila can drive 5.5 more miles per gallon than Julieta.

Since 132 is greater than or equal to 120, the inequality is satisfied.

Let's start by defining some variables:

Let "c" be the number of computers that Ms. Sanchez sells next week.

Let "E" be her total earnings for the week.

We know that she earns $72 per week plus $15 for every computer she sells, so we can write the expression for her total earnings as:

[tex]E = 72 + 15c[/tex]

Now we need to write an inequality using "c" for the number of computers she needs to sell in order to earn at least $120 next week. That is, we want to find the value of "c" that makes her earnings at least $120:

E ≥ 120

Substituting the expression for E, we get:

[tex]72 + 15c \geq 120[/tex]

Simplifying this inequality, we can start by subtracting 72 from both sides:

[tex]15c \geq 48[/tex]

Then, we can divide both sides by 15 (keeping in mind that we need to reverse the inequality direction when dividing by a negative number):

[tex]c \geq 3.2[/tex]

Therefore, Ms. Sanchez needs to sell at least 4 computers next week (since she can't sell a fraction of a computer). We can check this by plugging in c = 4 into the expression for E:

[tex]E = 72 + 15(4) = 132[/tex]

As a result, the geometric sequence's sixth term, which has a ratio of 2/3 and a first term of 2, is 32/243.

A mathematical series known as a geometric sequence is one in which each term following the first is obtained by multiplying the previous term by a constant, non-zero quantity known as the common ratio2. To put it another way, it is a sequence in which each term (aside from the initial term) is multiplied by a fixed amount to obtain the subsequent term1.

For instance, the geometric sequence 1, 2, 4, 8, 16,... has a common ratio of 2, since each item after the first is derived by multiplying the previous term by 2.

Aₙ = a₁× r(n-1) is the formula for the nth term of a geometric series, where a1 is the first term and r is the common ratio.

The common ratio in this instance is 2/3, and the first term is 2.

As a result, the sequence's nth term is represented by the formula

a = 2 × (2/3)(n-1).

We change n = 6 in the formula to get the sixth term in the sequence.

A₆ = 2× (2/3)⁵

Answer:

the mean absolute deviation for the given data set is 1.86.

Step-by-step explanation:

To find the mean absolute deviation, we first need to find the mean of the data set.

Mean = (1.25 + 3.50 + 2.55 + 8.20 + 4.80 + 0.30 + 0.75 + 2.25) / 8 = 3.07

Next, we find the absolute deviation of each data point from the mean by subtracting the mean from each data point and taking the absolute value:

|1.25 - 3.07| = 1.82

|3.50 - 3.07| = 0.43

|2.55 - 3.07| = 0.52

|8.20 - 3.07| = 5.13

|4.80 - 3.07| = 1.73

|0.30 - 3.07| = 2.77

|0.75 - 3.07| = 2.32

|2.25 - 3.07| = 0.82

Then, we find the mean of these absolute deviations:

Mean absolute deviation = (1.82 + 0.43 + 0.52 + 5.13 + 1.73 + 2.77 + 2.32 + 0.82) / 8

Mean absolute deviation = 1.86

Therefore, the mean absolute deviation for the given data set is 1.86.

To determine the probability that the herd's daily production will be between 32.3 and 36.9 liters, we must compute the z-scores for each number and use a standard normal distribution table to calculate the area under the curve between those z-scores.

To find out the z - scores we need use z-score formula:

Z = X−μ / σ

where μ  is the mean, σ is the standard deviation and X is the observed value. In the problem μ  is 30 liters, X₁ = 32.3 liters & X₂ = 36.9 liters and σ = 8.2 liters.

Substituting the values in the equation to find the z-score for 32.3 liters is:

z₁ = (32.3 - 30) / 8.2 = 0.2804

z₁ = 0.28049

Substituting the values in the equation to find the z-score for 36.9 liters is:

z₂ =( 36.9 - 30) / 8.2 =  0.8414

z₂ = 0.8414

We can determine the area under the curve between these two z-scores using a conventional normal distribution table. The area between z = 0.28049 and z = 0.8414 and the probability is approximately 0.1894.

Since we know that the distance between the origin and A' should be d, which is 7/3 times the distance between the origin and A.

Therefore, the correct answer is D.

What is Pentagon?

A pentagon is a geometric shape that has five sides and five angles. It is a two-dimensional polygon, which means it is a flat shape with straight sides.

To find the coordinates of the dilated pentagon A'B'C'D'E', we need to multiply the coordinates of each vertex of pentagon ABCDE by the scale factor. Since the origin is the center of dilation, we can use the formula:

(x', y') = k(x, y)

where (x, y) are the original coordinates of a vertex, k is the scale factor, and (x', y') are the new coordinates of the corresponding vertex.

To find the scale factor, we can use the distance formula to find the distance between the origin and any one of the vertices. Let's use vertex A for convenience:

Distance OA = sqrt((-1-0)² + (1-0)²) = sqrt(2)

Distance OA' = k * Distance OA

We want to find the scale factor that will result in a dilation centered at the origin, so we want OA' to be the desired distance between the origin and A'. Let's say that distance is d. Then:

d = k * sqrt(2)

Solving for k, we get:

k = d / sqrt(2)

We are not given the desired distance between the origin and A', so we cannot determine the exact value of k. However, we can still determine which answer choice represents the correct dilation.

Let's try answer choice A:

(x', y') = (3/7x, 3/7y)

This represents a dilation with a scale factor of 3/7. But we already know that the scale factor should be d / sqrt(2). Since d could be any value, we cannot say for sure whether 3/7 is the correct scale factor.

Answer choice B:

(x', y') = (x + 3/7, y + 3/7)

This represents a translation, not a dilation. Therefore, it cannot be the correct answer.

Answer choice C:

(x', y') = (x + 7/3, y + 7/3)

This represents a dilation with a scale factor of 1. This is not the correct scale factor, since we know that the distance between the origin and A' should be greater than the distance between the origin and A.

Answer choice D:

(x', y') = (7/3x, 7/3y)

This represents a dilation with a scale factor of 7/3. This is the correct scale factor, since we know that the distance between the origin and A' should be d, which is 7/3 times the distance between the origin and A.

Therefore, the correct answer is D.
