Answer:

Other than one, products to prime numbers.

Step-by-step explanation:

1=1x1 (But 1 isn't prime, so it's the exception.)

3=1x3 (1 isn't prime, but it'll pass.)

6=2x3 (Prime and prime)

10=2x5(Prime and prime)

15=3x5(Prime and Prime)

I also guess you could call these NOT prime numbers, because you can't call these composite, since one is neither prime or composite.

Determine the payment to amortize the debt. (Round your answer to the nearest cent.) Quarterly payments on $19,500 at 3.9% for 6

Olin [163]

Answer:

$925.20

Step-by-step explanation:

Loan Amount, P = $19,500

Rate of interest, r = 3.9%

Time, t = 6 years

Payment mode, n = Quarterly (4)

payment to amortize, EMI = ?

Formula: $EMI=\dfrac{P\cdot \frac{r}{n}}{1-(1+\frac{r}{n})^{-n\cdot t}}$

where,

n = 4 , Rate of interest , r = 0.039

Put the values into formula

$EMI=\dfrac{19500\cdot \frac{0.039}{4}}{1-(1+\frac{0.039}{4})^{-4\cdot 6}}$

$EMI=915.20$

Hence, The payment to amortize the debt is $915.20
