ANSWER

22.4 feet

EXPLANATION

The area of a rectangle is the product of its length and width,

We know that the area of this rectangle is 8w+18,

Divide both sides by w to solve for l,

We have to solve this for w = 1.25 ft,

Hence, the length of the rectangle is 22.4 feet.

After calculation we find out the expected value of Y is 6.29.

The expected value of Y can be calculated using the given relationship between X and Y, as well as the mean and variance of X. The relationship is Y = 1.90X + 6.29, where the mean of X is 0, and the variance of X is 1.

Step 1: Calculate the expected value of Y using the mean of X.
E(Y) = E(1.90X + 6.29)

Step 2: Apply the linearity property of expectation.
E(Y) = 1.90 * E(X) + E(6.29)

Step 3: Substitute the given mean of X (0) into the equation.
E(Y) = 1.90 * 0 + 6.29

Step 4: Calculate value of Y.
E(Y) = 6.29

The expected value of Y is 6.29.

Answer:

Number of sundaes = 36

Number of banana split = 28

Step-by-step explanation:

On that day, let the number of sundaes sold be x

Now, since they sold 8 more sundaes than banana, the number of bananas sold is x-8

So the cost of sundaes sold will be 2 * x = 2x

the total cost of banana splits sold will be 3(x-8) = 3x -24

The addition of both equals 156

Hence;

2x + 3x-24 = 156

5x -24 = 156

5x = 156 + 24

5x = 180

x = 180/5

x = 36

So

number of sundaes sold is 36 while the number of bananas split sold is 36-8 = 28

The result of an average of more than 100% in a survey of tenants on cleaning chores in shared apartments is likely due to social desirability bias.

The average tenant response of more than 100% in a study about cleaning duties in shared apartments is probably the product of social desirability bias. Social desirability bias occurs when respondents give answers that they think are socially acceptable or desirable, rather than their true opinions or behavior.

In this case, tenants may have overstated their contribution to cleaning the apartment, in order to appear more helpful or responsible, leading to an average percentage higher than 100%.

The percentage of IQ scores greater than 64 is 100% - 1.06% = 98.94%.

We need to use the standard normal distribution and the standard score (z-score) formula to convert IQ scores to standard normal values in order to find the percentage of IQ scores greater than 64.

The standard scoring formula is as follows:

z = (x - μ) / σ

where x is the IQ score, is the IQ distribution's mean (98), and is the IQ distribution's standard deviation (17).

So, for an IQ of 64, the standard score is:

z = (64 - 98) / 17 = -2.35

With the standard score in hand, we can use a standard normal table or a z-score calculator to calculate the percentage of IQ scores greater than 64. A z-score of -2.35 indicates a probability of 0.0106. This means that 1.06% of IQ scores less than or equal to 64.

Therefore, the percentage of IQ scores greater than 64 is 100% - 1.06% = 98.94%.

The consumption next year for Ms. Anderson will be approximately $56,363.64 which is not in options, and the debt-equity ratio, based on a total debt ratio of 0.5, so the answer is option d.

To answer the first question, we need to calculate the consumption next year based on the given information. We can use the concept of present value to determine the amount.

The present value formula is:

Present Value = Future Value / (1 + Interest Rate)^n

Where:

Future Value is the amount to be received in the future

Interest Rate is the rate of return or interest rate per period

n is the number of periods

Given that Ms. Anderson has an income of $40,000 next year and the market interest rate is 10 percent, we can calculate the present value of $40,000:

Present Value = $40,000 / (1 + 0.10)^1

Present Value = $40,000 / 1.10

Present Value ≈ $36,363.64

Since Ms. Anderson consumes $80,000 this year and her present income next year is approximately $36,363.64, her consumption next year will be the sum of her present income and the remaining amount:

Consumption next year = Present income + Remaining amount

Consumption next year = $36,363.64 + ($80,000 - $60,000)

Consumption next year = $36,363.64 + $20,000

Consumption next year = $56,363.64

Therefore, the consumption next year will be approximately $56,363.64. None of the provided options match this amount, so it seems there might be an error in the answer choices.

Given that the total debt ratio is 0.5, it implies that the total debt is half of the total equity.

The debt-equity ratio is calculated by dividing the total debt by the total equity:

Debt-Equity Ratio = Total Debt / Total Equity

Substituting the given information, we have:

Debt-Equity Ratio = 0.5 * Total Equity / Total Equity

The term "Total Equity" cancels out, resulting in:

Debt-Equity Ratio = 0.5

Therefore, the correct answer is option d. 0.5.

Step-by-step explanation:

when 2 triangles are similar, it means that both have the same angles. and that then all the corresponding side lengths relate to each other by the same multiplication factor.

PQ and ST are corresponding sides.

the length of ST (4) is the length of PQ (16) multiplied by 1/4.

16 × 1/4 = 4.

the same factor (1/4) also applies to the other sides.

and therefore,

TU = QR × 1/4 = 19.2 × 1/4 = 19.2/4 = 4.8

To solve for C let us do these steps

1. Put the term of C on one side and the other terms on the other side

Subtract 32 from both sides to move the term 32 to the other side

2. Make the coefficient of C = 1

Divide both sides by 9/5

The inequality which are true is 10pi>30 option B and pi+4>7 option D

In mathematics, "inequality" refers to a connection between two expressions or values that are not equal to one another.

In mathematics, larger than symbol (>), less than symbol (), less than or equal to symbol (), and not equal to symbol () are the five inequality symbols.

When resolving an inequality, you can do one of the following: • Add the same amount to each side; • Subtract the same amount from each side; • Multiply or divide each side by the same positive amount. You must flip the inequality sign if you multiply or divide either side by a negative number.

We know the value of pi is 3.14
