Answer:

Standard error of mean = 689
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $28,520
Standard Deviation, σ = $5600
Mean of sampling distribution =

As per Central Limit Theorem, if the sample size is large enough, then the sampling distribution of the sample means follow approximately a normal distribution.
Sample size, n = 66
Since the sample size is large, we can use normal distribution for approximation.
Standard error of mean =

Answer:
A. 
Step-by-step explanation:
We need to determine whether the polynomial
can be factored into perfect squares. If so, factor the polynomial. Otherwise, select that it cannot be factored into a perfect square.









Hence choice A.
is correct.
4/9*3/9= 12/81=4/27
You have a 4 in 27 chance of drawing a red then a blue.
