Answer: $5656.85
Step-by-step explanation:
The standard error of the mean measures the dispersion of sample means about the population mean .
It is also known as the standard deviation of its sampling distribution.
Formula : 
, where 
= population standard deviation.
n= sample size.
As per given , we have
sample size : n= 50
Then, the standard error of the mean will be :-
Hence, the standard error of the mean= $5656.85
Answer:
60

Step-by-step explanation:
Answer:
DF ≅ AC
Step-by-step explanation:
To prove that the triangles are congruent by AAS, we need a side from each triangle to be congruent to the other, correspondingly. So, if AC ≅ DF, we could prove the triangle's congruency by AAS. In the answer choices, the only answer that works is DF ≅ AC.
