Compound Interest Formula:
A = P(1 + r/n)^(nt)

A= Accumulated amount with interest P= principal= $1000
R= annual interest rate (decimal)= 0.05
N= # times compounded per year= 12
T= # of years= 10

A= 1000(1 + 0.05/12)^(12*10)
divide inside parentheses first

A= 1000(1 + 0.0041666667)^ (12*10)
add inside parentheses

A= 1000(1.0041666667)^ (12*10)
multiply exponents

A= 1000(1.0041666667)^120
multiply parentheses by exponents

A= 1000(1.6470095043)
multiply last two numbers

A= $1,647.01 amount after 10 years

ANSWER:
D) $1647.01 total after 10 years

Assume that there are 22 frozen dinners: 12 pasta, 6 chicken, and 4 seafood dinners. The student selects 5 of them. What is the

Stells [14]

Since, there are 22 frozen dinners. Out of these, 22 are pasta, 6 chicken and 4 seafood dinners.

We have to determine the probability that at least 2 of the dinners selected are pasta dinner. At least 2 of the dinners selected are pasta, it means that there can be 2 pasta, 3 , 4 or 5.

So, Probability with at least 2 of dinners

= $\frac{(^{12}C_{2} \times ^{10}C_{3})+ (^{12}C_{3} \times ^{10}C_{2})+(^{12}C_{4} \times ^{10}C_{1})+(^{12}C_{5})}{^{22}C_{5}}$
