Percentage of bills for which payment was made in greater than 42 days.

is 2.5%

In statistics, the 68–95–99.7 rule, also known as the empirical rule, is a shorthand used to remember the percentage of values that lie within an interval estimate in a normal distribution: 68%, 95%, and 99.7% of the values lie within one, two, and three standard deviations of the mean, respectively.

Given,

Mean μ = 28

Deviation σ = 7 days

Empirical Formula:

μ ± 2σ

= 28 ± 2(7)

= 28 ± 14

= [14, 42]

The empirical rule shows that 95% of the distribution lies within two standard deviation, in this case, from 14 to 42 days.

Thus, the remaining 5% of the distribution lies outside this range.

One half lies above 42 and the other below 14.

So, the probability of payment was made in greater than 42 days is 2.5%.

Hence, 2.5% of bills were paid in greater than 42 days.

The smallest number a such that A + BB is regular for all B > a can be determined by finding the eigenvalues of the matrix A. The value of a will be greater than or equal to the largest eigenvalue of A.

A matrix A is regular if it is non-singular, meaning it has a non-zero determinant. We can consider the expression A + BB as a sum of two matrices. To ensure A + BB is regular for all B > a, we need to find the smallest value of a such that A + BB remains non-singular. One way to check for singularity is by examining the eigenvalues of the matrix A. If the eigenvalues of A are all positive, it means that A is positive definite and A + BB will remain non-singular for all B. In this case, the smallest number a can be taken as zero. However, if A has negative eigenvalues, we need to choose a value of a greater than or equal to the absolute value of the largest eigenvalue of A. This ensures that A + BB remains non-singular for all B > a.

They weigh the pros and cons of each alternative, considering factors such as feasibility, risks, costs, benefits, and consequences. By asking about the advantages and disadvantages of each alternative, decision makers can systematically compare and contrast their options, identify potential trade-offs, and select the best alternative based on their criteria and preferences.

In a multiple regression model, the error term ε is assumed to satisfy certain assumptions for accurate statistical analysis and inference. The assumptions made about the error term are crucial for valid statistical analysis and inference.

In multiple regression, the error term ε represents the discrepancy between the observed data and the predicted values from the regression model. The assumptions made about the error term are crucial for valid statistical analysis and inference.

The error term ε is assumed to have a mean of zero, indicating that, on average, the predicted values align with the observed data. This assumption allows the regression model to capture the systematic relationship between the independent variables and the dependent variable.

Additionally, the error term is assumed to be independent and identically distributed (IID). This means that the errors for each observation are unrelated and have the same probability distribution. The independence assumption ensures that the errors do not exhibit any systematic patterns or correlations, allowing for reliable statistical analysis. The identical distribution assumption allows for the use of statistical techniques that rely on certain distributional properties, such as hypothesis testing and confidence intervals.

Furthermore, it is commonly assumed that the error term ε follows a normal distribution. This assumption enables the use of statistical techniques based on the normal distribution, such as estimating parameters and conducting hypothesis tests using t-statistics.

Overall, these assumptions about the error term in a multiple regression model are essential for valid statistical analysis and inference, ensuring accurate interpretation of the model's coefficients and significance tests.

The infinite geometric series 1 - 1/5 + 1/25 - 1/125 + ... is convergent and the sum of this infinite geometric series is 5/6.

To determine whether the infinite geometric series is convergent or divergent, and to find its sum if convergent, we'll consider the given series: 1 - 1/5 + 1/25 - 1/125 + ...

Step 1: Identify the common ratio (r).
In a geometric series, each term is a constant multiple of the previous term.

In this case, we can see that the common ratio is -1/5 because each term is obtained by multiplying the previous term by -1/5.

Step 2: Determine convergence or divergence.
An infinite geometric series converges if the absolute value of the common ratio (|r|) is less than 1, and diverges if |r| is greater than or equal to 1.

Since |-1/5| = 1/5 < 1, the series is convergent.

Step 3: Calculate the sum.
For a convergent geometric series, the sum can be found using the formula:
Sum = a / (1 - r)
where 'a' is the first term and 'r' is the common ratio.

In this case, a = 1 and r = -1/5, so:

Sum = 1 / (1 - (-1/5))
Sum = 1 / (1 + 1/5)
Sum = 1 / (6/5)
Sum = 5/6

Therefore, the sum of the infinite geometric series 1 - 1/5 + 1/25 - 1/125 + ... is 5/6.

D.  They do not have the same ratio of girls to boys because a straight line cannot be drawn through the points (14, 16), (17, 19), and (0, 0) on a coordinate grid.

Step-by-step explanation:

In order to check if the ratio is the same, convert the ratios to (x, y) points, plot them on a graph and see if you can draw a straight line through them and the origin (0, 0).  If you can, then the ratios are the same.  If not, then the ratios are not the same.

After plotting (14, 16) and (17, 19) and (0, 0) on a graph (attached), you can see that a straight line will only go through any two of the points, but not all three.  Therefore, the ratios are not the same.

Answer:

The tape worm is 60 feet long, while the round worm is 9 feet long.

Step-by-step explanation:

Let L be the length of the tapeworm and L' be the length of the round worm.

Given that the longest tape worms measured was 3 feet less than seven times the length of the longest round worm, we have

L = 7L' - 3  (1)

Also, since  if you leave these two worms and they would measure an amazing 69 feet, then L + L' = 69 (2)

Substituting equation (1) into (2), we have

L + L' = 69

7L' - 3 + L' = 69

collecting like terms, we have

8L' = 69 + 3

8L' = 72

L' = 72/8

L' = 9 feet

Substituting L' into (1), we have

L = 7L' - 3

L = 7(9) - 3

L = 63 - 3

L = 60 feet.

So, the tape worm is 60 feet long, while the round worm is 9 feet long.

Answer:

a. The company's profit function P(x, y, z) = 24x +12y +16z – 0.2x^2 – 0.1y^2 – 0.1z^2 – 26

b. The number of cars that must be sold in each market are 60 in America, also 60 in Europe and 80 in Asia.

Step-by-step explanation:

Note: This question is not complete and it has some errors in the figures used. The correct complete question is therefore provided before answering the question as follows:

An automobile manufacturer sells cars in America, Europe, and Asia, charging a different price in each of the three markets. The price function for cars sold in America is p = 27 − 0.2x  (for 0 ≤ x ≤ 135), the price function for cars sold in Europe is q = 15 − 0.1y  (for 0 ≤ y ≤ 150), and the price function for cars sold in Asia is r = 19 − 0.1z (for 0 ≤ z ≤ 190), all in thousands of dollars, where x, y, and z are the numbers of cars sold in America, Europe, and Asia, respectively. The company's cost function is C = 26 + 3(x + y + z) thousand dollars.

(a) Find the company's profit function P(x, y, z). [Hint: The profit will be revenue from America plus revenue from Europe plus revenue from Asia minus costs, where each revenue is price times quantity.]

P(x, y, z) =

(b) Find how many cars should be sold in each market to maximize profit. [Hint: Set the three partials Px, Py, and Pz equal to zero and solve. Assuming that the maximum exists, it must occur at this point.]

The explanation to the answers is now given as follows:

(a) Find the company's profit function P(x, y, z). [Hint: The profit will be revenue from America plus revenue from Europe plus revenue from Asia minus costs, where each revenue is price times quantity.]

p = price function for cars sold in America = p = 27 − 0.2x (for 0 ≤ x ≤ 135)

q = price function for cars sold in Europe = 15 − 0.1y (for 0 ≤ y ≤ 150)

r = price function for cars sold in Asia = 19 − 0.1z (for 0 ≤ z ≤ 190)

C = company's cost function = 26 + 3(x + y + z) = 26 + 3x + 3y + 3z

P(x, y, z) = profit function

x, y, and z are the numbers of cars sold in America, Europe, and Asia, respectively

Therefore, we have:

TR = Total revenue = px + qy + rz …………………………….. (1)

Substituting the relevant values into equation (1), we have:

TR = (27 − 0.2x)x + (15 − 0.1y)y + (19 − 0.1z)z

TR = 27x – 0.2x^2 + 15y – 0.1y^2 + 19z – 0.1z^2

Also,

P(x, y, z) = TR – C ……………………………………… (2)

Substituting the relevant values into equation (2), we have:

P(x, y, z) = 27x – 0.2x^2 + 15y – 0.1y^2 + 19z – 0.1z^2 – (26 + 3x + 3y + 3z)

P(x, y, z) = 27x – 0.2x^2 + 15y – 0.1y^2 + 19z – 0.1z^2 – 26 – 3x – 3y – 3z

P(x, y, z) = 27x – 3x +15y – 3y +19z – 3z – 0.2x^2 – 0.1y^2 – 0.1z^2 – 26

P(x, y, z) = 24x +12y +16z – 0.2x^2 – 0.1y^2 – 0.1z^2 – 26 ……………….. (3)

Therefore, the company's profit function P(x, y, z) = 24x +12y +16z – 0.2x^2 – 0.1y^2 – 0.1z^2 – 26.

(b) Find how many cars should be sold in each market to maximize profit. [Hint: Set the three partials Px, Py, and Pz equal to zero and solve. Assuming that the maximum exists, it must occur at this point.]

As indicated in the question, the number cars that should be sold in each market to maximize profit can be calculated by deriving the three partials Px, Py, and Pz from the profit function P(x, y, z), i.e. equation (3) in part a above, and set equal to zero and then solve as follows:

In America

From equation (3), we have:

Px = 24 – 0.4x = 0

Therefore, we have:

24 – 0.4x = 0

24 = 0.4x

x = 24 / 0.4

x = 60

In Europe

From equation (3), we have:

Py = 12 – 0.2y = 0

Therefore, we have:

12 – 0.2y = 0

12 = 0.2y

y = 12 / 0.2

y = 60

In Asia

From equation (3), we have:

Pz = 16 - 0.2z = 0

Therefore, we have:

16 - 0.2z = 0

16 = 0.2z

z = 16 / 0.2

z = 80

Based on the above calculations, the number of cars that must be sold in each market are 60 in America, also 60 in Europe and 80 in Asia.

To multiply a whole number and a fraction, you can first convert the whole number to a fraction by placing it over 1. Then, you can multiply the two fractions using the following formula:

a/b x c/d = ac/bd

Where a and c are the numerators of the fractions, and b and d are the denominators. After multiplying, you can simplify the resulting fraction, if necessary.

For example, to multiply 2 and 3/4, we can convert 2 to 2/1 and then multiply as follows:

2/1 x 3/4 = 6/4

Simplifying the resulting fraction, we get:

6/4 = 3/2

Therefore, 2 x 3/4 = 3/2.

One way to check your answer when multiplying fractions is to simplify both the numerator and denominator of the resulting fraction and compare it to the original fractions. If the simplified resulting fraction is equivalent to the original fractions, then the answer is correct.

Another way to check your answer is to divide the resulting fraction by one of the original fractions and see if the other original fraction is the quotient. For example, to check the answer to 2/3 x 3/4 = 1/2, we can divide 1/2 by 2/3 and see if the resulting quotient is 3/4:

(1/2) / (2/3) = (1/2) x (3/2) = 3/4

Since the resulting quotient is 3/4, which is equal to the other original fraction, 2/3 x 3/4 = 1/2 is correct.
