.0166
Step-by-step explanation:
Central Limit Theorem for proportions:
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean 
and standard deviation 
In this question:
What is σρˆ?
The standard deviation of the sample proportion, which is:
Answer:
9k+2m
Step-by-step explanation:
-9(-5k+3m)+9m-4(-5m+9k)
45k-27m+9m+20m-36k
45k-36k-27m+9m+20m
9k+2m
I know that x=-3. So probably that second choice.
Answer:
Step-by-step explanation:
The area of a circle is pi((r)^2)
And diameter = 2r
so 96 = 2r and the radius is 48 yards
Now plug in into A = pi(r)^2
=pi(48)^2 = 7234.56 yards^2.
