Answer:
Interest earned = $32.835
Step-by-step explanation:
Given the following data;
Principal = $275
Number of times = 0.5
Interest rate = 2.9% = 0.029
Time = 4 years
To find the interest earned, we would use the compound interest formula;
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
n is the number of times the interest is compounded in a year.
t is the number of years for the compound interest.
Substituting into the equation, we have;

A = $307.835
Interest earned = 307.835 - 275
Interest earned = $32.835

Answer:
Step-by-step explanation:
Total students = 120
Number of students studying Mathematics P(A) = 90
Number of students studying Science P(B) = 72
Number of students who doesn't study both subjects P(AUB)'= 10
1) Number of students studying atleast on subject = 120 -10 = 110
2) Number of students studying both math and science = (90 +72) -110
= 162 -110 = 52
3) Number of students studying only mathematics = 90 -52 = 38
4) Number of students studying only science = 72 -52 = 20
