Answer:
FICA tax should his employer withhold be $24.92 .
Option (D) is correct .
Step-by-step explanation:
As given
Bill’s FICA tax is 7.65% of his earnings of 325.78 per week.
7.65 % is written in the decimal form.
= 0.0765
FICA tax price = 0.0765 × Earning of a week
Putting values in the above
FICA tax price = 0.0765 × 325.78
= $ 24.92 (Approx)
Therefore the FICA tax should his employer withhold be $24.92 .
Option (D) is correct .
Answer: For 95% Confidence Interval:
Upper Limit = 110.2
Lower Limit = 97.8
95% Confidence Interval = [97.8, 110.2]
Step-by-step explanation:
Given that,
Mean(M) = 104
Standard Deviation(SD) = 10
Sample Size(n) = 10
Formula for calculating 95% Confidence Interval are as follows:
Standard error(SE) =
=
= 3.164
⇒ M ± × SE
= 104 ± (1.96)(3.164)
= 104 ± 6.20
∴ Upper Limit = 104 + 6.20 = 110.2
Lower Limit = 104 - 6.20 = 97.8
So,
95% Confidence Interval = [97.8, 110.2]

Q2:
Step-by-step explanation:
The derivative of the product of two functions is:
The derivative is the product of the first function and the derivative of the second function added to the product of the second function and the derivative of the first function.
Q1: The function you are given is:
You can think of that function as the product of functions
and
We first find the derivatives of functions u and v:
