There are 20 students in the high school glee club. They need to pick four students to serve as
gayaneshka [121]

Answer:

4845 ways

Step-by-step explanation:

To solve this problem we use the formula of combinations

nCr=\frac{n!}{r!(n-r)!}

Where n is the total number of students that can be chosen and you choose r from them.

So

n = 20\\r = 4

Note that in this case the order in which the 4 students are chosen does not matter.

Then

20C4=\frac{20!}{4!(20-4)!}

20C4=\frac{20!}{4!*16!}=4845\ ways

Robin, who is self-employed, contributes $4500/year into a Keogh account. How much will he have in the account after 30 years if
pashok25 [27]

Answer:

The amount that would be in the account after 30 years is $368,353

Step-by-step explanation:

Here, we want to calculate the amount that will be present in the account after 30 years if the interest is compounded yearly

We proceed to use the formula below;

A = [P(1 + r)^t-1]/r

From the question;

P is the amount deposited yearly which is $4,500

r is the interest rate = 2.5% = 2.5/100 = 0.025

t is the number of years which is 30

Substituting these values into the equation, we have;

A = [4500(1 + 0.025)^30-1]/0.025

A = [4500(1.025)^29]/0.025

A = 368,353.3309607034

To the nearest whole dollars, this is;

$368,353
