Find the periodic payment R of a loan with a present value PV of $18,000 and an annual interest rate r 5.4% for a term of t 6 years, with payments made and interest charged 12 times per year.

  $293.24

Step-by-step explanation:

The amortization formula is good for this. (So are any number of financial calculators or apps.)

  R = PV(r/n)/(1 -(1 +r/n)^(-nt))

for present value PV, annual interest rate r, term t in years, and n the number of compoundings per year.

  R = $18,000(0.054/12)/(1 -(1 +0.054/12)^(-12·6)) ≈ $293.24

The periodic payment is $293.24.

every other student who enters the school

Step-by-step explanation:

It is given that the middle school students have an average height of 5.25 feet. The students belongs to Seton Grove School.

It means that every student who comes to this school or enters the school has a height that is around 5 feet or more.

Thus we can say that every other student who enters the school has a average height of 5.25 feet.

This sample makes the generalization about the heights of the school students valid.
