Answer:

<u>The correct answer is B. US$371.32</u>

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Loan that Jesse's Mother did to Jesse = US$ 350

Duration of the loan = 2 years

Annual interest rate = 3% compounded annually

2. Let's find the future value of this loan after 2 years, using the following formula:

FV = PV * (1 + r) ⁿ

PV = Loan that Jesse's Mother did to Jesse = US$ 350

number of periods (n) = 2

rate (r) = 3% = 0.03

Replacing with the real values, we have:

FV = 350 * (1.03) ²

FV = 350 * 1.0609

FV = 371.32

<u>Jesse will pay his mom back altogether US$ 371.32.</u>

SCCoast, an Internet provider in the Southeast, developed the following frequency distribution on the age of Internet users. Fin

Tomtit [17]

Answer:

Mean: 40.17 years.

Standard deviation: 10.97 years.

Step-by-step explanation:

The frequency distribution is in the attached image.

We can calculate the mean adding the multiplication of midpoints of each class and frequency, and dividing by the sample size.

The midpoints of a class is calculated as the average of the bounds of the class.

Then, the mean can be written as:

$E(X)=\dfrac{1}{N}\sum f_iX_i\\\\\\E(X)=\dfrac{1}{60}(3\cdot15+7\cdot25+18\cdot35+20\cdot45+12\cdot 55)=\dfrac{45+175+630+900+660}{60}\\\\\\E(X)=\dfrac{2,410}{60}=40.17$

The standard deviation can be calculated as:

$s=\sqrt{\dfrac{1}{N-1}\sum f_i(X_i-E(X))^2}\\\\\\s=\sqrt{\dfrac{1}{59}[3(15-40.17)^2+7(25-40.17)^2+18(35-40.17)^2+20(45-40.17)^2+12(55-40.17)^2]}$

$\\\\\\s=\sqrt{\dfrac{1}{59}( 1,900.59 + 1,610.90 + 481.12 + 466.58 + 2,639.15 )}\\\\\\s=\sqrt{\dfrac{ 7,098.33 }{59}}=\sqrt{120}=10.97$
