Answer:
His balance is $4,849.65 after 5 years
Step-by-step explanation:
A = P(1 + r/n)^nt
A = future value = ?
P = present value = $4,500
r = interest rate = 1.5% = 0.015
n = number of periods = 4
t = time = 5 years
A = P(1 + r/n)^nt
= 4,500(1 + 0.015/4)^4*5
= 4,500(1 + 0.00375)^20
= 4,500(1.00375)^20
= 4,500(1.0777)
= 4,849.65
A = $4,849.65
His balance is $4,849.65 after 5 years
The 99% confidence interval for the population mean is 6± 2.443
<h3>Confidence interval</h3>
The formula for calculating the confidence interval is expressed as:
CI = x± z(s/√n)
GIven the following parameters
x = 6
s = 3
n = 10
z score at 99% = 2.576
Substitute into the formula to have:
CI = 6± 2.576(3/√10)
CI = 6± 2.443
Hence the 99% confidence interval for the population mean is 6± 2.443

Equation:
37 = 12x
37 / 12 = x
3.0833... = x
