The correct answer is d that is because if it is 1 onch per 15 miles then do 11x15 and you get 165 c and d are the only 2 close enough to be it but from there you can cancel c because its 11.3 which means it must be more than 165. and d is the only one that is greater then 165

Step-by-step explanation:
7.51% = . 0751 as a decimal. (. 0751) * $45,000 = $3,379.50.
Answer:
Sample size n = 1382
so correct option is D) 1382
Step-by-step explanation:
given data
confidence level = 99 %
margin of error = 3%
probability = 25 %
to find out
How large a sample size needed
solution
we know here P = 25 %
so 1 - P = 1 - 0.25
1 - P = 0.75
and we know E margin of error is 0.03 so value of Z for 99%
α = 1 - 99% = 1 - 0.99
α = 0.01
and
= ![\frac{0.01}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B0.01%7D%7B2%7D)
= 0.005
so Z is here
= 2.576
so
sample size will be
Sample size n = ![(\frac{(Z_(\frac{\alpha}{2})}{E})^2 * P * (1-P)](https://tex.z-dn.net/?f=%28%5Cfrac%7B%28Z_%28%5Cfrac%7B%5Calpha%7D%7B2%7D%29%7D%7BE%7D%29%5E2%20%2A%20P%20%2A%20%281-P%29)
put here value
Sample size n = (\frac{2.576}{0.03})^2 * 0.25 * 0.75
Sample size n = 1382
so correct option is D) 1382
