Answer:

9 inches²

Step-by-step explanation:

Since a square has 4 equal sides, we can divide its perimeter by 4 to find the length of a single side.

12/4 = 3

Each side of the square is 3 inches long.

To find the area of the square, then, multiply the length, 3 and the width, 3, together.

3 · 3 = 9

The area of the square is 9 inches.

When choosing a bank, consider fees for services such as ATM transactions and debit card usage, as well as factors such as availability of free checking, customer service, and rewards/interest rates.

First State Bank:

Total check fees = 5 checks x $1/check = $5

Total ATM fees = 3 ATM transactions x $1/transaction + 2 nonbank ATM transactions x $2/transaction = $7

Total debit card fees = 8 debit card transactions x $0/debit card transaction = $0

Total monthly fees = $12.50

Total fees = $5 + $7 + $12.50 = $24.50

National Bank:

Total check fees = 5 checks x $1/check = $5

Total ATM fees = 3 ATM transactions x $0/transaction + 2 nonbank ATM transactions x $2/transaction = $4

Total debit card fees = 8 debit card transactions x $0/debit card transaction = $0

Total monthly fees = $0

Total fees = $5 + $4 + $0 = $9

Third City Bank:

Total check fees = 3 checks x $0/check = $0

Total ATM fees = 3 ATM transactions x $0/transaction + 2 nonbank ATM transactions x $3/transaction = $6

Total debit card fees = 8 debit card transactions x $0.75/debit card transaction = $6

Total monthly fees = $0

Total fees = $0 + $6 + $6 + $0 = $12

When choosing which of the three banks to use for making debit purchases, you might consider factors such as the availability of free checking, the fees for nonbank ATM transactions, the fees for debit card transactions, and the level of customer service provided by each bank. Additionally, you might consider the interest rates and rewards offered by each bank for maintaining a checking account with them.

If you're given two different coordinates, and you want to find the slope, the general rule is that you subtract the first coordinates from the first. The formula for these kinds of problems is \(\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\) .

1. The linear equation is T = 20 + 15W, where W is the weight of the chicken in kg.

2. The cooking time is 1 hour and 5 minutes.

3. The weight of the chicken is 6.67 kg.

1. The formula to calculate the time taken (T) to cook a full chicken would be:

T = 20 + 15W, where W is the weight of the chicken in kg.

2. If the weight of the chicken is 3kg, then the time taken to cook the chicken would be:

T = 20 + 15(3) = 65 minutes

Converting 65 minutes to hours and minutes, we have 1 hour and 5 minutes.

3. Let's say the weight of the chicken is W kg. Then, the time taken to cook the chicken would be:

T = 20 + 15W

We also know that it took 120 minutes to prepare and cook the chicken. So, we can write:

120 = 20 + 15W

15W = 100

W = 100/15 kg (rounded to two decimal places)

Therefore, the weight of the chicken is approximately 6.66666666667

The sample would be representative of the population, and the statistics calculated from the sample would accurately reflect the characteristics of the population.

However, in practice, it is often difficult to achieve a perfectly representative sample.

Sampling bias, which occurs when some members of the population are more likely to be selected than others, can lead to differences between the sample and population averages.

The investment will be worth approximately $28,940 at age 67.  The average rate of return on the investment is approximately 5.59%.

To calculate the future value of an investment and the average rate of return, we'll consider two scenarios: one with monthly compounding and one with annual compounding.

1. Monthly Compounding:

Given that you earn 0.8% per month in the stock market, we can calculate the future value of your $10,000 investment when you reach age 67. Since we don't have the exact age, we'll assume it to be 21 years and 1 month for this calculation.

To calculate the future value with monthly compounding, we use the formula:

FV = PV * (1 + r)^n

Where:

FV = Future Value

PV = Present Value (initial investment)

r = Monthly interest rate

n = Number of compounding periods

In this case, PV = $10,000, r = 0.008 (0.8% monthly interest rate), and n = (67 - 21) * 12 (number of months from age 21 to 67).

Using the formula, we can calculate the future value:

FV = $10,000 * (1 + 0.008)^((67 - 21) * 12)

We can simplify the equation and calculate the value:

FV ≈ $10,000 * (1.008)^576

FV ≈ $10,000 * 2.894

FV ≈ $28,940

Therefore, the investment will be worth approximately $28,940 at age 67.

2. Annual Compounding:

Given that the value of your $10,000 investment at age 67 is $350,000, we can calculate the average rate of return over the investment period.

To calculate the average rate of return, we use the formula:

Average Rate of Return = (FV / PV)^(1/n) - 1

Where:

FV = Future Value

PV = Present Value (initial investment)

n = Number of years

In this case, FV = $350,000, PV = $10,000, and n = 67 - 21 (investment period).

Using the formula, we can calculate the average rate of return:

Average Rate of Return = ($350,000 / $10,000)^(1 / (67 - 21)) - 1

To solve the equation for the average rate of return:

Average Rate of Return = ($350,000 / $10,000)^(1 / 46) - 1

We can simplify the equation:

Average Rate of Return = 35^(1 / 46) - 1

Using a calculator, we can evaluate the expression:

Average Rate of Return ≈ 0.0559

Therefore, the average rate of return on the investment is approximately 5.59%.

From the Venn diagram , the value of  required probability P(A∪B) is given by :

Option a). 0.6 . The probability that students  takes both Spanish and Chemistry.

Let us consider 'A' be the probability of the students who takes Chemistry.

And 'B' be the probability of the students who takes Spanish.

From the Venn diagram we have,

Probability of A 'P(A) ' = 0.2 + 0.1

                                    = 0.3

Probability of B 'P(B)' = 0.3 + 0.1

                                   = 0.4

Probability of A∩B 'P(A∩B)' = 0.1

Probability of A∪B is given by :

P(A∪B) = P(A) + P(B) - P(A∩B)

Substitute the value we get ,

⇒ P(A∪B) = 0.3 + 0.4 - 0.1

⇒ P(A∪B) =  0.6

P(A∪B) represents the probability of the students that takes both Chemistry and Spanish.

We can conclude that only some of the ratios in Table A are greater than the ratios in Table B. (option-c)

To compare the ratios of squares to circles in the tables, we must divide the value in the Squares column by the value in the Circles column for each row in the table.

For Table A, the ratios of squares to circles are:

5/3 = 1.67

10/6 = 1.67

For Table B, the ratios of squares to circles are:

10/3 = 3.33

20/9 = 2.22

Comparing the ratios in Table A to the ratios in Table B, we see that the first two ratios are equal (1.67) and the last two ratios are different (3.33 in Table B is greater than 1.67 in Table A, and 2.22 in Table B is less than 1.67 in Table A).

The vector w is not in Col(A) because Ax=w is an inconsistent system. One row of the reduced row echelon form of the augmented matrix [A|w] is in the form [0 0 b] where b ≠ 0.

The vector w is not in Nul(A) because Aw ≠ 0.

To determine whether the vector w = [3 1] is in the column space of the matrix A = [−15 45 −5 15], we can row reduce the augmented matrix [A|w] and check if the resulting system is consistent.

[A|w] = [−15 45 −5 15 | 3 1]

Performing row reduction on [A|w], we get:

[1 -3 1/3 -1/3 | -1/5 0]

So, the system Ax = w is inconsistent, and therefore, w is not in the column space of A.

To determine whether the vector w is in the null space of A, we need to check if Aw = 0.

Aw = [−15 45 −5 15] [3 1]ᵀ = [(-15)(3) + (45)(1) + (-5)(0) + (15)(0) , (-15)(0) + (45)(0) + (-5)(3) + (15)(1)]ᵀ = [30, -30]ᵀ
