Answer:
$10,603.20
Step-by-step explanation:
You can calculate the simple interest of the loan using the formula:
I = prt, where I = interest, p = principal amount, r = interest rate and t = time. Plugging in the values from the problem:
p = $7,050
r = 8.4% or 0.084
t = 6 years
I = (7050)(0.84)(6) = $3,553.20
To find the total cost of the boat, add the interest and the purchase price:
$7,525 + $3,553.20 = $11,078.20
Answer:
A sample of 1077 is required.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is of:
42% of freshmen do not visit their counselors regularly.
This means that 
98% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
How large of a sample size is required?
A sample size of n is required, and n is found when M = 0.035. So
Rounding up:
A sample of 1077 is required.
