A researcher wants to determine if birthweights of children born to U.S. mothers is affected in any way when large megadoses of

caffeine are consumed routinely by the mother during pregnancy. It is known that the birthweights are normally distributed with mean 7.5 pounds and standard deviation 1 pound. When drawing a sample of size 40 from such a population, and computing the mean birthweight in the sample, use the Central Limit Theorem to find the 2.5-th percentile of the distribution of sample means.

ratelena [41]

Step-by-step explanation:

  1. a . write the formula for finding area that is area= L by W so to get w will area over length so 4731/83= 57
  2. perimeter=2( L+ W ) so substitute so that it looks like this 318= 2(L + 72 ) then open the bracket 318= (2L + 144) then move 144 to the other side so 318 - 144 = 2L then you get 174= 2L divide both sides by 2 and your length is 87

<h3>Answer: B) $878.28</h3>

================================================

Explanation:

She starts off $16.75 in debt

Later on she deposits $16.75 to get completely out of debt and make the balance 0. This is after depositing the $5.72

So far her balance is $5.72

Add on $872.56 to get 5.72+872.56 = 878.28

-------------

This is what your steps may look like

-16.75 + (5.72 + 16.75)

-16.75 + (16.75 + 5.72)

(-16.75+16.75) + 5.72

(0) + 5.72

5.72

5.72+872.56

878.28
