Answer: $8359 will be in the account after 9 years.
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 4500
r = 7% = 7/100 = 0.07
n = 2 because it was compounded 2 times in a year.
t = 9 years
Therefore,
A = 4500(1+0.07/2)^2 × 9
A = 4500(1+0.035)^18
A = 4500(1.035)^18
A = $8359
Answer:
the answer is 6 and 9
Step-by-step explanation:
6 x 2 is 12 and 12-3 is 9 added together they are 15
Answer: 601
Step-by-step explanation:
When the prior estimate of the population proportion is unavailable , then the formula to find the sample size is given by :-
, where E = margin of error
and z* = Critical z-value associated with the confidence level.
As per given , we have
The prior percentage of full-time college students who earn a bachelor's degree in four years or less is not given.
E= 0.04
We know that the critical value for 95% confidence level = z*= 1.960
Then , the required sample size is given by :-
Hence, the required sample size is 601.
