John invests $3,000 into an account that earns 4.7% interest compounded quarterly. Write an equation and us it to find the value

kow [346]

Answer:

The equation is;

A = 9,000(1 + 0.047/4)^48

The value is

$15,767.28

Step-by-step explanation:

Here we want to find the value of an investment after 12 years, given its interest rate;

Mathematically the amount which is the value would be;

A = I( 1 + r/n)^nt

Where A is the amount in 12 years

I is the initial amount invested = $3,000

r is the interest rate = 4.7% = 4.7/100 = 0.047

n is the number of times interest is compounded yearly = 4 since it is quarterly ( once every three months)

t is the number of years = 12

Substituting these values, we have

A = 9,000(1 + 0.047/4)^(12^4)

A = 9,000(1 + 0.047/4)^48

The above is the expression

A = 9,000(1 + 0.01175)^48

A = 9,000(1.01175)^48

A = $15,767.28

Sisters Amilia and Bianca play games together often. Let A represent the number of games Amilia wins monthly, and let B represen

Harman [31]

Using addition of variables, it is found that the mean of S is of 73 and the standard deviation is of 8.5.

<h3>What happens to the mean and the standard deviation when two variables are added?</h3>

The mean is the sum of the means.

The standard deviation is the square root of the sum of variances.

In this problem, for variables A and B, we have that:

$\mu_A = 35.5, \sigma_A = 5.1$

$\mu_B = 37.3, \sigma_B = 6.8$

Variable S is the sum of A and B, hence:

$\mu_S = \mu_A + \mu_B = 35.5 + 37.3 = 73$

$\sigma_S = \sqrt{\sigma_A^2 + \sigma_B^2} = \sqrt{5.1^2 + 6.8^2} = 8.5$

The mean of S is of 73 and the standard deviation is of 8.5.

Jason is planning to replace carpet in the utility room of his house the length of the room is 8 feet and the width of the room

olganol [36]

Given Information:

Length of room = l = 8 feet

Width of room = w = 7 feet

Required Information:

Amount of carpet = ?

Answer:

Amount of carpet = 56 ft²

Step-by-step explanation:

Jason wants to replace the carpet in the utility room of his house.

We are given the dimensions of the room and we are asked to find the required amount of carpet in square feet.

The required amount of carpet is given by

$A = w\times l$

where w is the width of room and l is the length of the room.

$A = 7\times 8\\\\A = 56 \:$

Therefore, Jason need 56 square feet of carpet for the utility room.
