Answer:

The better deal is the 12 pack because the unit price is $0.37 which is lower than the unit price of the 18 pack that is $0.80.

Step-by-step explanation:

To find which is the better deal, you have to determine which one offers a lower unit price by dividing the price of each package by the number of balls in the pack:

$4.47/12=$0.37

$14.46/18=$0.80

According to this, the answer is that the better deal is the 12 pack because the unit price is $0.37 which is lower than the unit price of the 18 pack that is $0.80.

Value refers to the numerical quantity of a variable in an equation or problem. In this problem-solving equation, we are given 2x + y = a multiple of 5. To find three possible values of x and y, we need to consider different combinations of x and y that satisfy this equation.

a. To find three possible values of x and y, we can use trial and error. For example, we could let x = 1 and y = 3, which gives us 2(1) + 3 = 5, a multiple of 5. Another combination could be x = 2 and y = 1, which gives us 2(2) + 1 = 5. A third combination could be x = 3 and y = -1, which gives us 2(3) + (-1) = 5. Therefore, three possible values of x and y are (1,3), (2,1), and (3,-1).

b. Upon examining the values of x and y, we notice that all three solutions satisfy the original equation, 2x + y = a multiple of 5. Additionally, we can see that each value of x corresponds to a unique value of y that satisfies the equation. Therefore, we can conclude that there are multiple solutions to this problem, and the values of x and y can vary depending on the specific values of a and the conditions of the problem.

The sample of 395 boys obtained from a prospective epidemiological study had varying numbers of criminal record convictions. A mean of approximately 1.01 convictions per boy. The standard deviation is approximately 1.39 convictions.

The mean number of convictions for the sample can be calculated by summing up all the convictions and dividing by the total number of boys (395). In this case, the sum of the convictions is 265 + 49 + 21 + 19 + 18 + 10 + 2 + 2 + 4 + 2 + 1 + 3 + 1 + 2 = 399. Dividing this by 395 gives a mean of approximately 1.01 convictions per boy.

The variance measures the spread or dispersion of the data. To calculate the variance, we first subtract the mean from each conviction count, square the differences, sum them up, and divide by the total number of boys. The variance for this sample is calculated to be approximately 1.93 convictions.

The standard deviation is the square root of the variance and provides a measure of the average distance between each conviction count and the mean. In this case, the standard deviation is approximately 1.39 convictions.

The standard error estimates the variability of the sample mean. It is calculated by dividing the standard deviation by the square root of the sample size. Since the sample size is 395, the standard error for the number of convictions in this sample is approximately 0.07 convictions.

The range is the difference between the maximum and minimum values in the sample. In this case, the range for the number of convictions is from 1 to 14.  

To calculate the proportion of each category, divide the frequency of each conviction count by the total number of boys (395). For example, the proportion of boys with 1 conviction is 265/395 ≈ 0.67.

The cumulative relative frequency is obtained by adding up the proportions for each conviction count. For instance, the cumulative relative frequency for boys with 3 or fewer convictions is 0.89.

Finally, the cumulative frequency distribution graph visually represents the cumulative frequency of convictions, where the x-axis represents the conviction count and the y-axis represents the cumulative frequency.

Step-by-step explanation:

The expression that provides the volume of the pyramid is as follows;

As mentioned in the question

It is given that the pyramid put inside a prism

Also the pyramid contains the similar base area but the height is half of the prism

so the base area of the pyramid is b

And, the Height of the pyramid = h ÷ 2

Now as we know that  

The volume of the pyramid is

V = 1 ÷3 × base ares × height

= 1 ÷ 3 × b × h ÷ 2

V = 1 ÷ 6 bh

So, the volume is 1 ÷6 bh cube unit.

We get this by crossing off numbers (that have blue x's) from each side of the number line. You would keep crossing off numbers from both sides till you are left with 1 or 2 numbers. In this case, we are given a set of numbers with a total of 9 numbers so we don't have to worry about there being 2 numbers at the end.

Answer:

Step-by-step explanation:

Let's call the number of boys "b" and the number of girls "g". From the ratio, we know that b/g = 11/9.

Also, we know that b = g + 124, so we can substitute the second equation into the first:

b/g = 11/9

b = g + 124

g + 124 / g = 11/9

Cross multiply:

9g + 1112 = 11g

Solve for g:

-2g = -1112

g = 556

So there are 556 girls and 556 + 124 = 680 boys at the school.

The total number of students at the school is 556 + 680 = 1236.

Answer:

q= (23+8a)/a

Step-by-step explanation:

a(q-8)=23

or, aq-8a = 23

or, aq = 23+8a

or, q = (23+8a)/a

(I’m not sure if the A is part of the question or if A is what question you’re answering but I’ll work o for both)

A(q - 8) = 23

Multiply everything inside the brackets by A:

aq- 8a = 23

Divide both sides by a to isolate q - 8a:

q - 8a = 23 / a

Add 8a to both sides to isolate q:

q = 23 + 8a² / a

Without the A:

q - 8 = 23

Add 8 to both sides to isolate q:

q = 31

The weighted-average unit contribution margin is $46.20.

The weighted-average unit contribution margin can be calculated by multiplying the unit contribution margin of each model by its respective sales mix percentage, and then summing up the results.

To find the weighted-average unit contribution margin, we first calculate the unit contribution margin for each model by subtracting the unit variable costs from the selling price:

For Model A12:

Unit contribution margin = Selling price - Unit variable cost

                     = $60 - $42

                     = $18

For Model B22:

Unit contribution margin = Selling price - Unit variable cost

                     = $120 - $84

                     = $36

For Model C124:

Unit contribution margin = Selling price - Unit variable cost

                     = $480 - $360

                     = $120

Next, we multiply each unit contribution margin by its respective sales mix percentage:

Weighted contribution margin for Model A12 = 60% * $18 = $10.80

Weighted contribution margin for Model B22 = 15% * $36 = $5.40

Weighted contribution margin for Model C124 = 25% * $120 = $30.00

Finally, we sum up the weighted contribution margins:

Weighted-average unit contribution margin = $10.80 + $5.40 + $30.00 = $46.20. Therefore, the weighted-average unit contribution margin is $46.20.

(b) In this particular case, the power method will not produce meaningful results, and the eigenvalues and eigenvectors of matrix A cannot be accurately determined using this method.

To compute the iterations using the power method, we start with an initial vector u₀ and repeatedly multiply it by the matrix A, normalizing the result at each iteration. The eigenvalue corresponding to the dominant eigenvector will converge as we perform more iterations.

(a) Computing u₁, u₂, u₃, and u using the power method:

Iteration 1:

\(u₁ = A * u₀ = [[1 2] [-1 -1]] * [1, 1] = [3, -2]\)

Normalize u₁ to get\(u₁ = [3/√13, -2/√13]\)

Iteration 2:

\(u₂ = A * u₁ = [[1 2] [-1 -1]] * [3/√13, -2/√13] = [8/√13, -5/√13]\)

Normalize u₂ to get u₂ = [8/√89, -5/√89]

teration 3:

\(u₃ = A * u₂ = [[1 2] [-1 -1]] * [8/√89, -5/√89] = [19/√89, -12/√89]\)

Normalize u₃ to get u₃ = [19/√433, -12/√433]

The iterations u₁, u₂, and u₃ have been computed.

(b) The power method will fail to converge in this case because the given matrix A does not have a dominant eigenvalue. In the power method, convergence occurs when the eigenvalue corresponding to the dominant eigen vector is greater than the absolute values of the other eigenvalues. However, in this case, the eigenvalues of matrix A are 2 and -2. Both eigenvalues have the same absolute value, and therefore, there is no dominant eigenvalue.

Without a dominant eigenvalue, the power method will not converge to a single eigenvector and eigenvalue. Instead, the iterations will oscillate between the two eigenvectors associated with the eigenvalues of the same magnitude.

The data includes a concave mirror with a radius of curvature of +31.5 cm and magnification of m = 3.40. The formula for magnification is m = v/u, and the focal length is f = r/2. Substituting the values, we get u = v/m, and using the mirror formula, the distance of the object from the mirror is 10.15 cm.

Given data: Radius of curvature of a concave mirror, r = +31.5 cm Magnification produced by the mirror, m = 3.40

We know that the formula for magnification is given by:

m = v/u where, v = the distance of the image from the mirror u = the distance of the object from the mirror We also know that the formula for the focal length of the mirror is given by :

f = r/2where,f = focal length of the mirror

Using the mirror formula:1/f = 1/v - 1/u

We know that a concave mirror has a positive focal length, so we can replace f with r/2.

We can now simplify the equation to get:1/(r/2) = 1/v - 1/u2/r = 1/v - 1/u

Also, from the given data, we have :m = v/u

Substituting the value of v/u in terms of m, we get: u/v = 1/m

So, u = v/m Substituting the value of u in terms of v/m in the previous equation, we get:2/r = 1/v - m/v Substituting the given values of r and m in the above equation, we get:2/31.5 = 1/v - 3.4/v Solving for v, we get: v = 22.6 cm Now that we know the distance of the image from the mirror, we can use the mirror formula to find the distance of the object from the mirror.1/f = 1/v - 1/u

Substituting the given values of r and v, we get:1/(31.5/2) = 1/22.6 - 1/u Solving for u, we get :u = 10.15 cm

Therefore, the distance of the mirror from the face is 10.15 cm. The units are centimeters (cm).Answer: 10.15 cm.
