<u>Given</u>:
The given expression is 
We need to determine the values for which the domain is restricted.
<u>Restricted values:</u>
Let us determine the values restricted from the domain.
To determine the restricted values from the domain, let us set the denominator the function not equal to zero.
Thus, we have;
Taking square root on both sides, we get;
Thus, the restricted value from the domain is
Hence, Option A is the correct answer.

Answer:
45 workers.
Step-by-step explanation
In 90 hours 15 workers will build one wall
So in 90 hours it w1ll take 1 worker to build 1/15 of a wall.
In 30 hours he would build 1/45 of a wall.
So to build the whole wall in 30 days it will take 45 workers.
Answer: Estimated standard error for the sample mean difference would be 1.
Step-by-step explanation:
Since we have given that
Mean of MD = 4.90
So, Sum of difference would be
S = 288
n = 9
We need to find the standard error for the sample mean differences.
Estimated standard error for the sampled mean difference would be
Hence, estimated standard error for the sample mean difference would be 1.
