Answer:

<h3>20</h3>

Step-by-step explanation:

Standard deviation of the mean is expressed as:

SM = s/√n

s is the standard deviation of all invoices

n is the sample size of the invoiced

Given

s = $200

n = 100

Required

Standard deviation of the mean

Substitute the given parameters into the given equation

SM = 200/√100

SM = 200/10

SM = 20

Hence the standard deviation of xbar is 20

base=7.5

height=4

why , shouldn't we take 5(or)6 as height because we shouldn't take slanting lengths as height.

so apply base and height in the formula

7.5×4=30

The final amount of the compound interest after 6 years would be $ 294, 122, 500

<h3>How to determine the final amount</h3>

The formula for the final amount is given as;

A = P( 1 + \frac{r}{n}) ^n^t

Where

A = final amount

P = principal interest

r = interest rate

n = number of times

t = time of periods

We have,

A = 2500 ( 1 + \frac{6}{1}) ^1^*^6

A = 2500 ( 7)^6

A = 2500 × 117, 649

A =$ 294, 122, 500

Thus, the final amount of the compound interest after 6 years would be $ 294, 122, 500
