Factor out like terms
-y(7+y)=0
4,400 + 17,600 = 22,000.
4,400 / 22,000 = 0.2
0.2 = 20%
The answer is A.

Answer:15/2
Step-by-step explanation:
Answer:
a) 151lb.
b) 6.25 lb
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, a large sample size can be approximated to a normal distribution with mean
and standard deviation
.
In this problem, we have that:

So
a) The expected value of the sample mean of the weights is 151 lb.
(b) What is the standard deviation of the sampling distribution of the sample mean weight?
This is
