Answer:
The nominal annual interest rate is 15%.
The effective interest rate is 16.08%.
Step-by-step explanation:
$9,375 = $325 (P/A, i%, 36)(P/A, i%, 36)
= $9,375/$325= 28.846
From compound interest tables, i = 1.25%
Nominal Interest Rate= 1.25 x 12= 15%
Effective rate = (1+ (0.15/36))^36-1=1.004^36-1= 16.08%
All of them are except for number 1
Answer: 50%
There are 2 sides, one of which is tails, so
P(tail) = 1/2 = 0.50 = 50%
The sum of two adjacent sides is 11 inches, so the long sides are 9 inches. The "unknown number" must be 12.
