Any combination of sections of the same size can be used to represent the whole. Quantity is described as "a portion" under a particular measurement in Standard English. 8, 3/4. Fractions are included in wholes. These act as the ratio divisor, which is a pair of integers in mathematical words. Here are a couple of examples showing how to change straightforward halves into entire numbers.

Here,

Let's refer to the amount of rain that fell the previous week as x inches.

The information provided indicates that it rained 2 1/2 inches on Wednesday, which is 3/4 of an inch more than the quantity that fell the previous week. This knowledge can be expressed as an equation:

=> 2 1/2 = x + 3/4

=> 2 1/2 - 3/4 = x

=> 2 1/2 = 5/2

=> 3/4 = 3/4

=> 5/2 - 3/4 = x

In this instance, 2 and 4 have a common denominator of 4, which is 4. So, using 4 as the common denominator, we can rewrite the fractions as follows:

=> 5/2 - 3/4 = x

=> (5/2) × (2/2) - 3/4 = x

=> 10/4 - 3/4 = x

=> 7/4 = x

The density of a sample of an unknown substance with a mass of 6 grams and a volume of 12 cm³ is 0.5 grams.

Density is a fundamental physical property that measures the amount of matter (mass) packed into a particular space (volume). The mathematical definition of density is simply the mass of an object divided by its volume. Density is typically measured in units of mass per unit volume, such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). One crucial aspect of density is that it is an intrinsic property of a substance, meaning it is a characteristic that depends solely on the material and is not affected by the amount of the substance. By using density, we can identify the material a particular object is made of. For example, a piece of gold will have a higher density than a piece of silver because gold is a more dense metal. Additionally, the density of an object can be used to determine its buoyancy in a fluid. Objects with a higher density will sink in a fluid with a lower density, while objects with a lower density will float.

Density is defined as the amount of mass per unit of volume. Mathematically, it can be represented as:

Density = Mass/Volume

Substituting the given values, we get:

Density = 6 grams/12 cm³

Density = 0.5 grams/cm³

Therefore, the density of the sample is 0.5 grams/cm³.

The total amount of interest paid over the life of the loan is $1863.45.

The present value of the loan.

Since there are 12 months in a year, and the loan has n-years, there are 12n monthly payments.

Let's use the formula for the present value of an annuity due:

[tex]PV = PMT \times ((1 - (1 + r) ^(-n)) / r) \times (1 + r)[/tex]

PV is the present value of the loan, PMT is the monthly payment, r is the monthly interest rate, and n is the number of months.

Substituting the given values, we get:

[tex]PV = \$800 \times ((1 - (1 + 0.12/12) ^(-12n)) / (0.12/12)) \times (1 + 0.12/12)[/tex]

[tex]PV = \$800 \times ((1 - (1.01)^(-12n)) / 0.01) \times 1.01[/tex]

[tex]PV = \$800 \times ((1 - 1.01^(-12n)) / 0.01) \times 1.01[/tex]

[tex]PV = \$800 \times ((1 - 0.887^(-n)) / 0.01) \times 1.01[/tex]

The formula for the interest paid in any given month of an annuity due:

[tex]I = PV \times r \times (1 + r) ^(m - 1)[/tex]

I is the interest paid in the 45th month, PV is the present value of the loan, r is the monthly interest rate, and m is the month.

Substituting the given values for the 45th month, we get:

[tex]\$424.45 = PV \times 0.01 \times (1 + 0.01 )^(45 - 1)[/tex]

[tex]\$424.45 = PV \times 0.01 \times (1.01)^4^4[/tex]

[tex]PV = \$424.45 / (0.01 \times (1.01)^4^4)[/tex]

PV =[tex]\$75799.45[/tex]

Now that we know the present value of the loan, we can calculate the total amount of interest paid over the life of the loan.

Let's use the formula for the total interest paid in an annuity due:

[tex]Total interest = (PMT \times n \times (n + 1) / 2) - PV[/tex]

Substituting the given values, we get:

Total interest = [tex](\$800 \times 12n \times (12n + 1) / 2) - \$75799.45[/tex]

Total interest = [tex]\$9600n^2 + \$4800n - \$75799.45[/tex]

We can solve for n by using the fact that the interest paid in the 45th month is $424.45:

[tex]\$424.45 = \$800 \times (n \times 12 - 44) \times 0.01 \times (1 + 0.01)^(45 - 1)[/tex]

[tex]\$424.45 = \$800 \times (n \times 12 - 44) \times 0.01 \times (1.01)^4^4[/tex]

n = 4.5

Substituting n = 4.5 into the formula for total interest, we get:

Total interest =[tex]\$9600 \times (4.5)^2 + \$4800 \times 4.5 - \$75799.45[/tex]

Total interest = $1863.45

221x = 6269 * 1100

Dividing both sides by 221, we get:

x = 6269 * 1100 / 221

Simplifying, we get:

x = 31,245.25

Answer: 39°

Step-by-step explanation:

In an isosceles triangle, two sides are of equal length, and the angles opposite these equal sides are also equal. Let's call these two equal angles x. Given that one angle measures 102°, we can find the possible measures for the other two angles.

The sum of the interior angles of a triangle is always 180°. So, we have:

x + x + 102° = 180°

2x = 180° - 102°

2x = 78°

x = 39°

Therefore, the other two angles in the isosceles triangle are both 39°.

The probability of exponential random variables that your job will be ready before 10:01 is approximately 0.0693, or about 6.93%.

We can use the cumulative distribution function (CDF) of the exponential distribution to solve this problem. Let X be the random variable representing the time it takes to print a job. Then, X follows an exponential distribution with parameter λ = 1/12, since the expectation of X is 12 seconds.

The probability that your job will be ready before 10:01 is equal to the probability that the printer finishes the first two jobs in less than 1 minute since your job is third in line.

Let Y be the random variable representing the time it takes to print the first job. Then, Y also follows an exponential distribution with parameter λ = 1/12.

The probability that the first job is finished before 10:01 is given by:

P(Y < 60) = 1 - [tex]$e^{(-\lambda t)}$[/tex] = 1 - [tex]e^{(-(1/12)(60))}[/tex] = 0.3935

Similarly, the probability that the second job is finished before 10:01 is also 0.3935, since it is also an exponential random variable with the same parameter. Therefore, the probability that your job will be ready before 10:01 is:

P(X < 60) = P(Y < 60) × P(Y < 60) × P(X < 60) = 0.3935² × (1 - [tex]$e^{(-\lambda t)}$[/tex]) = 0.0693

Answer: Let's say we want to find out how many red Skittles we need to add to the bag to have the same ratio of red Skittles as in the original bag.

Suppose the original bag contains x red Skittles. Then, the ratio of red Skittles to the total number of Skittles in the bag is x/100.

Let's say we add y red Skittles to the bag, so the total number of red Skittles in the bag becomes x + y. The total number of Skittles in the bag becomes 100 + y, since we only added red Skittles.

For the ratio of red Skittles to be the same as in the original bag, we need:

(x + y) / (100 + y) = x / 100

Cross-multiplying, we get:

100(x + y) = x(100 + y)

Simplifying and rearranging, we get:

y = 100x / (100 - x)

So, we need to add 100x / (100 - x) red Skittles to the bag to have the same ratio of red Skittles as in the original bag. For example, if the original bag has 20 red Skittles, we need to add:

y = 100(20) / (100 - 20) = 25

So, we need to add 25 red Skittles to the bag to have the same ratio of red Skittles as in the original bag.

The variance of the area of the circle is [tex]\pi^2\theta^{4/45}[/tex].

The mean area of the circle is [tex]\pi\theta^{2/3}.[/tex]

Let X be the radius of the circle, uniformly distributed on [0, θ].

The probability density function of X is given by:

[tex]f(x) = 1/\theta, for 0 \leq x \leq θ[/tex]

= 0, otherwise

Let Y be the area of the circle. Then[tex]Y = \pi X^2.[/tex] We want to find the mean and variance of Y.

Mean of Y:

By the law of the unconscious statistician, the mean of Y is given by:

[tex]E(Y) = E(\pi X^2) = \pi E(X^2)[/tex]

[tex]E(X^2)[/tex] using the formula for the variance of X:

[tex]Var(X) = E(X^2) - [E(X)]^2[/tex]

Since X is uniformly distributed on [0, θ], we have:

[tex]E(X) = (0 + \theta)/2 = \theta/2[/tex]

[tex]Var(X) = [(\theta - 0)^2]/12 = \theta^{2/12}[/tex]

Solving for [tex]E(X^2)[/tex], we get:

[tex]E(X^2) = Var(X) + [E(X)]^2 = \theta^2/12 + (\theta/2)^2 = \theta^{2/3}[/tex]

Substituting this into the expression for E(Y), we get:

[tex]E(Y) = \pi E(X^2) = \pi (\theta ^{2/3}) = \pi \theta^{2/3}[/tex]

Variance of Y:

To find the variance of Y, we can use the formula for the variance of a function of a random variable:

[tex]Var(Y) = E(Y^2) - [E(Y)]^2[/tex]

We can find[tex]E(Y^2)[/tex] using the law of the unconscious statistician:

[tex]E(Y^2) = E[(\pi X^2)^2] = \pi^2E(X^4)[/tex]

To find [tex]E(X^4)[/tex], we can use the formula for the fourth moment of a uniform distribution:

[tex]E(X^4) = (\theta^4 + 2\theta^2)/5[/tex]

Substituting this into the expression for[tex]E(Y^2)[/tex], we get:

[tex]E(Y^2) = \pi^2E(X^4) = \pi^2[(\theta^4 + 2\theta^2)/5] = \pi^2\theta^{4/5} + 2\pi^2\theta^{2/5}[/tex]

Substituting this and the expression for E(Y) into the formula for the variance of Y, we get:

[tex]Var(Y) = E(Y^2) - [E(Y)]^2[/tex]

[tex]= \pi^2\theta^{4/5} + 2\pi^2\theta^{2/5} - (\pi\theta^2/3)^2[/tex]

If the customers arriving at "checkout-counter" in a department store follow a Poisson distribution, then probability of exactly 5 customers arriving in one hour is approximately 0.1277 or 12.77%.

The "Poisson-Distribution" is defined as a discrete probability distribution which represents the number of events occurring in a "fixed-interval" of time, given a known "average-rate" of occurrence.

In this case, the average-rate of customer arrivals is 7 customers per hour.

Let "average-rate" be "λ = 7",

We need to find the probability of exactly "5-customers" arriving in one hour, which means we need to calculate P(X = 5), where X follows a Poisson distribution with λ = 7.

The Poisson probability mass function (PMF) formula is:

⇒ P(X=x) = (λˣ × e⁻ˣ))/x!

where:

P(X=k) is the probability of X taking the value "x",

λ = average rate parameter. "e" = Euler's number,

"x" = number of events, "x!" = factorial of x,

Substituting the values of λ = 7, k = 5,

We get,

⇒ P(X=5) = (7⁵ × e⁻⁷)/5!,

⇒ P(X=5) ≈ 0.1277,

There are a total of 99 positive integers less than 100 (from 1 to 99, inclusive).

We want to count the number of integers that are not multiples of 2 or 3.

The number of integers that are multiples of 2 is 49 (from 2 to 98, inclusive, with a common difference of 2).

The number of integers that are multiples of 3 is 33 (from 3 to 99, inclusive, with a common difference of 3).

However, we have double-counted the integers that are multiples of both 2 and 3 (i.e., multiples of 6). There are 16 such integers (from 6 to 96, inclusive, with a common difference of 6).

Therefore, the number of integers that are not multiples of 2 or 3 is:

99 - (49 + 33 - 16) = 83

Segment CP is tangent to circle C at point B.

How to prove that the line is tangent to a circle?

Draw circle C with center at point A and radius AD = CD = DE.

Draw point P outside the circle C.

Draw segment AP and extend it to intersect the circle at point B.

Draw segment BD.

Draw segment CP.

Note that triangle BCD is isosceles, since CD = BD. Therefore, angle BDC = angle CBD.

Since angle BDC is an inscribed angle that intercepts arc BC, and angle CBD is an angle that intercepts the same arc, then angle BDC = angle CBD = 1/2(arc BC).

Since CD = DE, then angle CED = angle CDE. Therefore, angle DCE = 1/2(arc BC).

Since angles BDC and DCE are equal, then angles BDC and CBD are also equal, and triangle BPC is isosceles. Therefore, segment BP = segment PC.

Since BP = PC, then segment CP is perpendicular to segment BD, by the Converse of the Perpendicular Bisector Theorem.

The volume of the solid is 4,503.22 in³.

What is volume?

A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder, or a sphere. Different shapes have different volumes

The volume of a solid with a hollow cylinder can be calculated by subtracting the volume of the inner cylinder from the volume of the outer cylinder.

Assuming the dimensions in the figure are in inches, the outer cylinder has a height of 17 inches and a radius of 9 inches, so its volume is:

[tex]V_{outer} = \pi * r^2 * h[/tex]

= π × 9² × 17 ≈ 4,842.51 in³

The inner cylinder has a height of 12 inches and a radius of 3 inches, so its volume is:

[tex]V_{inner} = \pi * r^2 * h[/tex] = π × 3² × 12 ≈ 339.29 in³

To find the volume of the solid, we need to subtract the volume of the inner cylinder from the volume of the outer cylinder:

[tex]V_{solid }= V_{outer} - V_{inner}[/tex]

≈ 4,842.51 - 339.29 ≈ 4,503.22 in³

[tex]= lim_n→∞ |(x+8) / 4| * |ln(n+1) / ln(n)|[/tex]

For the series to converge, this limit need to be less than 1. therefore, we've:

[tex]|(x+8) / 4| * lim_n→∞ |ln(n+1) / ln(n)| < 1[/tex]

For the reason that[tex]lim_n→∞ |ln(n+1) / ln(n)| = 1[/tex], we will simplify this to:

|(x+8) / 4| < 1

Taking the absolute cost under consideration, we have cases:

Case 1: (x+8)/4 < 1

In this case, we have x < -4.

Case 2: (x+8)/4 > -1

In this case, we have x > -12.

Consequently, the radius of convergence is the distance from the center of the collection (x = -8) to the closest endpoint of the c language (-12 on the left and -4 at the right):

This means that any point on the circle (x + 6)² + (y + 4)² = 36 is 6 units away from the signal located at (-6, -4).

To visualize this, imagine the signal as a point source located at (-6, -4), and the range of the signal as a circle centered at the signal with a radius of 6. Any point on this circle represents the farthest distance that the signal can reach and still be detected.

In summary, the signal is located at (-6, -4) and its range is 6 units, as represented by the circle (x + 6)² + (y + 4)² = 36.

Answer:

[tex]y = \frac{1}{3} x + 3[/tex]

Step-by-step explanation:

Start at the point (-3, 2). Go up 1 unit, then right 3 units, to the point (0, 3). The slope of the line is 1/3, and the y-intercept is 3, so we have
