Answer:
He will need 4 newborns in the sample to be 95% confident.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the length of the sample.
So:
He will need 4 newborns in the sample to be 95% confident.
Answer:
10
Step-by-step explanation:
10x0 is 0
10x1 is 10
Area = 18x^2 + 69x + 60
Width = 3x + 4
Length = (18x^2 + 69x + 60) ÷ (3x + 4)
Length = 3(3x + 4)(2x + 5) ÷ (3x + 4)
Length = 3(2x+5)
