Answer:
D 200 and 2
Step-by-step explanation:
standard error of the sampling distribution of sample mean is expressed using the formula;
Standard error of the mean = S/√n where;
S is the standard deviation
n is the sample size
Given
S = 18
n = 81
SEM = 18/√81
SEM = 18/9
SEM = 2
The mean of the distribution according to the question is 200.
Hence the mean and the standard error of the sampling distribution of sample mean are 200 and 2 respectively.

The relationship between the number of pentagons and the perimeter will be

From the diagram in the question, each side of a pentagon has length
.
Also, each time another pentagon is attached, a side is removed.
Using these observations, we can create a relationship between the number of pentagons,
, and the perimeter,
, as follows
For
