The final answer is a. probability that at least one of the bonds default is 0.9.

                                b. probability that neither of the bonds default is 0.10.

                                c. probability that the seven-year AA-rated bond defaults, the probability that the seven-year A-           rated bond also defaults is 0.244.

a. The probability that at least one of the bonds defaults can be calculated using the formula:

P(A or B) = P(A) + P(B) - P(A and B)

Where A represents the default of the seven-year AA-rated bond and B represents the default of the seven-year A-rated bond.

P(A or B) = 0.41 + 0.59 - 0.10 = 0.90

So, the probability that at least one of the bonds defaults is 0.90.

b. The probability that neither bond defaults can be calculated as:

P(not A and not B) = 1 - P(A or B) = 1 - 0.90 = 0.10

So, the probability that neither the seven-year AA-rated bond nor the seven-year A-rated bond defaults is 0.10.

c. Given that the seven-year AA-rated bond defaults, the probability that the seven-year A-rated bond also defaults can be calculated using conditional probability:
P(B | A) = P(A and B) / P(A) = 0.10 / 0.41 ≈ 0.244

So, given that the seven-year AA-rated bond defaults, the probability that the seven-year A-rated bond also defaults is approximately 0.244.

Then,

The triangle has lengths of 59 feet, 66 feet, and 79 feet.

Let us represent the length of the shortest side of the triangle with x feet, and that of the other shorter side with y feet

The longest side will be (2x - 39) feet

The length of the other shorter side will give us the equation;

y + x = 2x - 39 + 46

so that by subtracting x from both sides, we have

y = 2x - x + 46 - 39

y = (x + 7) feet

From the question,

x + x + 7 + 2x - 39 = 204 feet {which is the perimeter of the triangle}

4x - 32 = 204 {collect like terms}

4x = 203 + 32

4x = 236

x = 236/4

x = 59 feet

Therefore, as the length of the shortest side of the triangle is 48 feet,

the other shorter side is;

y = 59 + 7

y = 66 feet

and the longest side is;

2(59) - 39

118 - 39

79 feet.

The space cost you $833.33. per MONTH

To calculate the monthly cost, we first need to determine the annual cost of the space.

Given that the cost is $10 per square foot per year, we know, there are 12 months in an year and the space is 1,000 square feet, the annual cost of the space would be:

Annual cost = the space  * cost

Annual cost = 1,000 square feet * $10/square foot = $10,000

To convert this to monthly cost, we divide the annual cost by 12 (the number of months in a year):

Monthly cost = $10,000 / 12 = $833.33

Therefore, the monthly cost of the 1,000 square feet of space in the new building would be $833.33.

You will be able to withdraw approximately $3,076.32 at the end of 5 years.

To calculate the amount you will be able to withdraw at the end of 5 years, we can use the future value formula for compound interest.

The formula for calculating the future value (FV) of a present value (PV) invested at an annual interest rate (r) for a certain number of years (t) is:

\(FV = PV * (1 + r)^t\)

Given:

PV = $2,300

r = 6% = 0.06 (decimal representation)

t = 5 years

Substituting these values into the formula, we get:

FV = $2,300 * \((1 + 0.06)^5\)

Calculating the expression inside the parentheses:

\((1 + 0.06)^5 = 1.338225\)

Multiplying the present value by this factor:

FV = $2,300 * 1.338225

FV ≈ $3,076.32

The percentage of Measurements that are 124.4 or higher is approximately 0.99%.

In order to determine the percentage of measurements that are 124.4 or higher in a population of measurements that is approximately normal with a mean of 95 and a standard deviation of 15, we need to use the z-score formula.

The z-score formula is used to standardize a distribution so that it can be compared to a normal distribution with a mean of 0 and a standard deviation of 1.

The formula for calculating the z-score is: z = (x - μ) / σWhere:x is the measurement we want to standardize.μ is the population mean.σ is the population standard deviation.

The first step is to calculate the z-score for the measurement of 124.4:z = (124.4 - 95) / 15z = 2.2933The second step is to find the percentage of measurements that are 124.4 or higher using a standard normal distribution table. We look up the area to the right of the z-score of 2.2933 in the table.

The closest value in the table is 0.9901, which corresponds to a z-score of 2.33. We know that the area to the left of a z-score of 2.33 is 0.9901, so the area to the right of a z-score of 2.33 is:1 - 0.9901 = 0.0099

This means that approximately 0.99% of the measurements are 124.4 or higher.

Therefore, the percentage of measurements that are 124.4 or higher is approximately 0.99%.
