The diagram shows a square pizza box with side lengths of 12 inches. In the box is a circular pizza with a radius of 5 inches. What is the difference between the area of box and the pizza? Use π = 3.14 and round your answer to the nearest hundredth.

You are c) a structure. A structure is a collection of one or more different types of variables, including arrays and pointers, that have been grouped under a single name for each manipulation.

A structure is a user-defined data type that allows you to group together related data. For example, you could create a structure to store the name, age, and address of a person. The structure would have three variables, each of a different type: a string variable for the name, an integer variable for the age, and a string variable for the address.

The advantage of using a structure is that it allows you to treat the related data as a single unit. This makes it easier to manipulate the data and to pass the data to functions.

The other answer choices are incorrect. A template is a blueprint for creating a generic class or function. An array is a collection of elements of the same type. Local variables are variables that are declared within a function and that are only accessible within the function.

Answer:

Length of sides ;

3.5 yards ; 10 yards.

Step-by-step explanation:

Let :

Side 1 = x

Side 2 = y

x = 2y + 3

Perimeter (P) of rectangle = 2(side1 + side2)

Perimeter, P = 27

P = 2(x + y)

27 = 2(2y + 3 + y)

27 = 2(3y + 3)

27 = 6y + 6

27 - 6 = 6y

21 = 6y

y = 21/6

y = 3.5

From ; x = 2y + 3

x = 2(3.5) + 3

x = 7 + 3

x = 10

Length of the other side of the rectangle will be 10 yards.

       Perimeter of a rectangle = 2(Length + Width)

Given in the question,

Let one side of the rectangle = x yards

Therefore, other side of the rectangle = (2x + 3) yards

Substitute the values in the expression for the perimeter,

Perimeter = 2[x + (2x + 3)]

27 = 2(3x + 3)  [Simplify the equation]

27 = 6x + 6

6x = 21

x = 3.5 yards

Other side of the rectangle = (2x + 3) yards

                                              = 2(3.5) + 3

                                              = 10 yards

      Therefore, length of the other side of the rectangle will be 10 yards.

Answer: twice 31 and 13 = 75

Step-by-step explanation: 31 + 31 = 62 + 13 = 75

Answer:

some information is missing, so I looked for similar questions and found the attached image:

free cash flow = net income + non-cash expenses - capital expenditures - increase in net working capital

free cash flow for current year = $7,600 - $1,140 - $10 = $6,450 million

the firm's total value = ($6,450 x 1.0462) / (13.86% - 4.62%) = $6,747.99 / 9.2% = $74,977.67 million

the value of common stocks = firm's total value - value of outstanding debt - preferred stocks = $74,977.67 - $31,412 - $17,451 = $26,114.67 million

intrinsic value per share = $26,114.67 / 150 = $174.10 per stock

No, we cannot conclude that the coin is not fair at a 5% level of significance.

To determine whether the coin is fair or not, we can perform a hypothesis test using the binomial distribution. The null hypothesis (H0) assumes that the coin is fair, meaning that the probability of getting a head is 0.5. The alternative hypothesis (H1) assumes that the coin is not fair.

In this case, the observed number of heads in 500 flips is 220. To test the hypothesis, we can calculate the p-value, which represents the probability of obtaining a result as extreme or more extreme than the observed result, assuming the null hypothesis is true.

Under the null hypothesis, the expected number of heads in 500 flips would be 0.5 * 500 = 250. We can use the binomial distribution to calculate the probability of getting 220 or fewer heads out of 500 flips, assuming the probability of success is 0.5.

By using statistical software or tables, we can find that the probability of getting 220 or fewer heads is relatively high. Let's assume it is 0.10 (10%).

The p-value is the probability of observing a result as extreme or more extreme than the observed result, given the null hypothesis is true. In this case, the p-value is 0.10.

Since the p-value (0.10) is higher than the chosen significance level (0.05), we fail to reject the null hypothesis. This means that we do not have enough evidence to conclude that the coin is not fair at a 5% level of significance.

Therefore, based on the given data, we cannot conclude that the coin is not fair at a 5% level of significance. It is possible that the observed deviation from the expected number of heads is due to random chance rather than indicating a biased coin.

There are different ways that a person can contract hepatitis C. One way is through exposure to infected blood and bodily fluids. In the case of a person's professional occupation, certain occupations have a higher risk of exposure to infected blood and bodily fluids than others.

Therefore, the probability that a person with hepatitis C was infected in the course of his or her professional occupation depends on the nature of the occupation.

Occupations that have a higher risk of exposure to infected blood and bodily fluids include healthcare workers, emergency responders, and certain types of laboratory workers. People who inject drugs or who have received blood transfusions or organ transplants before 1992 are also at a higher risk of contracting hepatitis C.

However, it's important to note that many people with hepatitis C don't know how they contracted the virus, as it can be asymptomatic for years before symptoms appear. Therefore, it's difficult to determine the exact probability of a person being infected in the course of his or her professional occupation without knowing more information about the individual and their occupation.

The angle of elevation of the ladder is approximately 78.7 degrees. The ladder reaches approximately 22.2 ft high on the building.

To find the angle of elevation of the ladder, we can use trigonometry. The angle of elevation is the angle between the ladder and the ground.

Given:

Length of the ladder (hypotenuse) = 23 ft

Distance of the base of the ladder from the base of the building (adjacent side) = 6 ft

To find the angle of elevation (θ), we can use the inverse tangent function (arctan) with the ratio of the opposite side to the adjacent side:

\(\theta = tan^{-1}(opposite/adjacent)\)

In this case, the opposite side is the height the ladder reaches on the building.

Using the Pythagorean theorem, we can find the height (opposite side):

\(Height^2 = Length of the ladder^2 - Distance of the base^2\\Height^2 = 23^2 - 6^2\\Height^2 = 529 - 36\\Height^2 = 493\\Height = \sqrt{493}\)

Now, we can calculate the angle of elevation:

\(\theta = tan^{-1}(opposite/adjacent)\\\theta = tan^{-1}(\sqrt{493} / 6)\)

Calculating this value, we find:

θ ≈ 78.7 degrees (rounded to one decimal place)

Therefore, the angle of elevation of the ladder is approximately 78.7 degrees.

To find how high the ladder reaches on the building, we substitute the calculated value of the height:

Height = \(\sqrt{493}\)

Height ≈ 22.2 ft (rounded to one decimal place)

Therefore, the ladder reaches approximately 22.2 ft high on the building.

The basic idea is that multiplying by 10 just moves the decimal point one place to the right.  It makes the number bigger.

4.8 x 10 = 48

4.8 x 10 x 10 = 48 x 10 = 480

Each time you multiply by another 10, the decimal point moves one more time.

The expression \(10^5\) says you're going to multiply by 10 five times in a row.  So that will move the decimal point 5 places to the right.

So what do you get if you move the decimal in 4.8 five places to the right?

Answer:

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

When you get the reflecting coordinates along x-axis, the signs of the y coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:

A(9, 3), B(6, -4), and C(-1, 5).

When you get the reflecting coordinates along y-axis, the signs of the x coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:

Answer:

D

Step-by-step explanation:

The correct answer is (b) divide the sum of the cross-products of Z scores by the sample size.

When calculating the correlation coefficient, also known as Pearson's correlation coefficient, the last step involves dividing the sum of the cross-products of Z scores by the sample size. The correlation coefficient measures the strength and direction of the linear relationship between two variables.

To calculate the correlation coefficient, we follow these steps:

Standardize the variables: Convert the raw scores of each variable into Z-scores. The Z-score represents the number of standard deviations a particular score is from the mean. This step is done to put both variables on the same scale and make them comparable.

Calculate the cross-products: Multiply the Z-scores of the corresponding pairs of observations. This step gives us the cross-products of Z-scores for each pair of observations.

Sum the cross-products: Add up all the cross-products of Z-scores.

Divide by the sample size: Divide the sum of the cross-products of Z-scores by the sample size. The sample size represents the number of paired observations used in the analysis.

By dividing the sum of the cross-products by the sample size, we obtain the covariance of the variables. The covariance measures the extent to which the variables vary together. However, the covariance itself is not sufficient to determine the strength and direction of the relationship.

The final step involves dividing the covariance by the product of the standard deviations of the variables. This step normalizes the covariance and results in the correlation coefficient, which is a value between -1 and 1. The correlation coefficient indicates the strength and direction of the linear relationship between the variables. A positive correlation coefficient indicates a positive linear relationship, a negative correlation coefficient indicates a negative linear relationship, and a correlation coefficient close to zero indicates a weak or no linear relationship.

Therefore, the last step in calculating the correlation coefficient is to divide the sum of the cross-products of Z-scores by the sample size.

The value of AB in the geometry is 24 units.

According to the diagram,

BD ≅ BC

BD = 5x - 26

BC = 2x + 1

AC = 43

Therefore, the value of AB can be found using the knowledge of geometry.

BD = BC

5x - 26 = 2x + 1

5x  - 2x = 1 + 26

3x = 27

divide both sides by 3

x = 27 / 3

x = 9

Therefore,

BC = 2x + 1 = 2(9) + 1 = 18 + 1 = 19
