Answer:

1. Kevin has 12 pieces of paper.

2. Including Sybill and her friends, each person will get 1/8 of the 1/2 slice.

Step-by-step explanation:

1. This is because if 1 piece of paper turned divided into fourths would 4/1 or 4 “fourths” of paper. So multiply that by 3 since there is 3 pieces of paper and we are following the same steps. 3 x 4 = 12. Hence if you divide 3 pieces of paper into fourths, you will have 12 fourths.

2. Since we are splitting the 1/2 piece four (which includes sybill and her 3 friends) ways, the equation would be: 1/2 divided by 4

Divide:

1/2 divided by 4-

 1/2 : 4 = 1/2 · 1/4 = 1 · 1/2 · 4 = 1/8 

Hence, each friend and Sybill her self will receive a 1/8 piece.

The total volume of milk would be 1/2 gallons.

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.

Given that,

Volume = 1/4 gallons

The number of weeks = 2

So, the total volume =

1/4 × 2 = 1/2 gallons

Hence, the total volume of milk would be 1/2 gallons

In statistics, p represents the true proportion p hat represents the sample proportion

p represents population that has a certain characteristic or falls into a certain category. It is a fixed, unknown value that we are trying to estimate.

p hat represents the sample proportion, which is an estimate of the true proportion based on a sample of the population. It is calculated by dividing the number of individuals in the sample with the characteristic or in the category by the total sample size.

For example, if we want to estimate the proportion of students who prefer chocolate ice cream, we could take a sample of 100 students and find that 60 of them prefer chocolate.

In this case, p hat would be 60/100 or 0.6. This is our estimate of the true proportion, p, of all students who prefer chocolate ice cream.

When performing a t-test assuming unequal variances, the test statistic is a t-value, which is calculated by dividing the difference between the means of the two groups by the standard error of the difference.

To see if the difference in mean mpg between 4 and 8 cylinder cars is statistically significant, compare the estimated t-value to a critical t-value based on degrees of freedom and desired level of significance. The difference is regarded statistically significant if the estimated t-value is bigger than the crucial t-value.

Answer: The student correctly wrote an expression to find the total cost of downloading "s" songs. The expression is: 0.99s + 7.99. However, they made a mistake when they simplified the expression to 8.98s. The expression should have remained as 0.99s + 7.99, because the $7.99 membership fee does not change regardless of how many songs are downloaded.

In Part B, the student correctly used the expression to find the cost of downloading 12 songs. They multiplied 8.98 by 12 and got the correct answer of 107.76.

Step-by-step explanation:

The solution for r in the equation is 428.43

From the question, we have the following parameters that can be used in our computation:

100000 = 8000(1+ r/12000)^72

Divide through by 8000

So, we have

12.5 = (1+ r/12000)^72

Take the 72th root of both sides

So, we have

1 + r/12000 = 1.03570211065

Subtract 1

r/12000 = 0.03570211065

So, we have

Barbara will therefore shell out $171.36 for the cost of shipping and handling.

The amount of money, or its equivalent, for which anything being offered for sale, purchased, or otherwise transacted. A price on someone's head is a sum provided for their capture, whether they are alive or dead.

We must calculate 28% of the chandelier's original purchase price in order to calculate the value Sarah will charge for shipping and handling.

Step 1

Calculate 28% of $612

We can multiply a value by 0.28 to get 28% of it, or reduce it by 100 & then multiply the result by 28. So:

28% of $612 = 0.28 x $612 = $171.36

Step 2

Add the cost of shipping and handling to the purchase price.

True. A simple random sample is a type of sampling method that is used to select a subset of observations from a larger population.

The key characteristic of a simple random sample is that each observation in the population has an equal probability of being selected to be part of the sample.

Mathematically, this can be expressed as follows: Let N be the population size, and let n be the sample size. Then, the probability of any specific sample of n observations being selected from the population is given by the formula:

P(Sample) = (n!/N!)/(N-n)!

where n! represents the factorial of n (n factorial), and (N-n)! represents the factorial of N-n.

This means that if we were to draw multiple simple random samples of the same size from the same population, each sample would have an equal probability of being selected.

In conclusion, a simple random sample is a method of selecting a subset of observations from a population that ensures that each observation has an equal probability of being selected, and that each sample has an equal probability of being selected.

The equation of parabola in vertex form is [tex]$$\boxed{x^2 - 6x + 9 = 0}$$[/tex]

To write the equation of a parabola in vertex form, we use the following formula:

[tex]$$(x-h)^2=4p(y-k)$$[/tex]

where (h,k) is the vertex and p is the distance between the focus and the vertex.

Given that the focus of the parabola is at (3, 2.5), we can determine that the vertex of the parabola is also at (3, 2.5). Let's substitute these values into the formula:

[tex]$$(x-3)^2=4p(y-2.5)$$[/tex]

To find the value of p, we need to use the fact that the distance between the focus and vertex is p. The distance formula is:

[tex]$$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$$[/tex]

Substituting the values we know:

[tex]$$\begin{aligned} d &= \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \ &= \sqrt{(3 - 3)^2 + (2.5 - 2.5)^2} \ &= 0 \end{aligned}$$[/tex]

Since d = 0, we know that p = 0 and the equation simplifies to:

[tex]$$(x-3)^2=0$$[/tex]

Expanding the left side:

[tex]$$x^2 - 6x + 9 = 0$$[/tex]

So the equation of the parabola in vertex form is:

[tex]$$\boxed{(x-3)^2=4 \cdot 0 (y-2.5)}$$[/tex]

The width of the river is calculated by the tangent of the angle will be 293 feet.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

Observing a river below from the top of a 450-foot cliff, a hiker. Her depression lies at an angle of 80° to the near bank and 50° to the far bank of the river.

The horizontal distance when the angle is 80° is given as,

tan 80° = 450 / x₁

x₁ = 84.64 feet

The horizontal distance when the angle is 50° is given as,

tan 50° = 450 / x₂

x₂ = 377.59 feet

The width of the river is given as,

6x = 62° - 32°

6x = 30°

x = 5°

angles on a straight line add up to 180

To calculate the percent change in renewable energy investment in the US from 2005 to 2018, you can use the following formula:

Percent change = ((Final value - Initial value) / Initial value) * 100%

In this case, the initial value is $11.4 billion in 2005 and the final value is $46.5 billion in 2018. Plugging these values into the formula, we get:

Percent change = (($46.5 billion - $11.4 billion) / $11.4 billion) * 100%

= ($35.1 billion / $11.4 billion) * 100%

= 3.085 * 100%

= 308.5%

So, the percent change in renewable energy investment in the US from 2005 to 2018 was 308.5%, a substantial increase over the 13-year period.

The required measures of length are, as follows:

GF = 11, GE = 28, DF = 28, HF = 14, and DG = 25.75.

A rectangle is defined as a four-sided shape with opposite sides that are equal in length and parallel to each other.

The lengths are given in the question, as follows:

DE = 11

GH = 14

Since DE and GF are opposite sides then both are equal.

So GF = 11

Here GH and HF are equal,

HF = 14

∵ GE = GH + HE = 14 + 14 = 28

As we know that the two lengths of the diagonals are equal in the rectangle.

So GE = DF

So DF = 28

Using the Pythagorean theorem, we have

DG² + GF² = DF²

DG² + 11² = 28²

DG² + 121 = 784

DG² = 663

DG = 25.75

Thus, the measures are, as follows:
