The answer should be 50.24 m
∵ The formula of the compound interest is

→ A is the new amount
→ P in the initial amount
→ r is the interest rate in decimal
→ n is the number of periods
→ t is the time
∵ The initial amount is 800 dollars
∵ The annual rate is 3% = 3/100 = 0.03
∵ It is a compounded annually
∴ n = 1
∵ t = 5 years
→ Substitute all of these values in the formula above

→ Use the calculator to find the answer
∴ A = 927.4192594 dollars
C. In similar triangles the angles remain the same
Answer:
Option c.
Step-by-step explanation:
Confidence interval refers to an interval such that there is a probability that the value of a parameter lies within that interval.
Therefore,
the confidence interval of the mean means that there is a probability that the value of a parameter lies within that confidence interval.
So, option c. is correct
