Answer:
AC=
Step-by-step explanation:
AC is the base, BC is the hypotenuse, so the side length is AB.
We are given that AC=7 units, and BC is equal to 8.
Thus we have 8^2-7^2=(AB)^2
64-49=(AC)^2
15=(AC)^2
AC=

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.
