Answer:
By the Central Limit Theorem, the best point estimate for the average number of credit hours per semester for all students at the local college is 14.8.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of the sample:
14.8 credit hours per semester.
So
By the Central Limit Theorem, the best point estimate for the average number of credit hours per semester for all students at the local college is 14.8.
Well 7/2=3.5 so i would say 3/1/2 i believe
A and e are congruent so e is 105 since h and e make a line they will add up to 180
180=105+h
H= 75
If the triangles are similar then
8~y and 6~9 divide 9 by 6 to get the scale factor this is how much the triangle enlarges by or shrinks by
9/6= 1.5 now that you know the scale factor you can find y y/8=1.5
Y= 12
