Answer:
(3, 0)
Step-by-step explanation:
The easiest way to do this problem is to average the x-coordinates and y-coordinates.
So, (0 + 6) / 2 = 6/2 = 3 = x and (2 - 2)/2 = 0/2 = 0 = y
Therefore, the midpoint is (3,0)
The sample size must be 543 so the sample proportion is will not differ by 5%
We are given the following in the question:
Margin of error = 5%
Confidence interval:
p ±z√(p'(1 - p')/n)
Margin of error =
p = ±z√(p'(1 - p')/n)
Since no particular proportion is given, we take
p' = 0.5
Z critical at α 0.02 is ± 2.33
Putting values, we get,
p = ±z√(p'(1 - p')/n)
2.33 x √(0.5(1 - 0.5)/n)
√n = 2.33x 0.5/0.05
n = 542.89 = 543
Thus, the sample size must be 543 so the sample proportion is will not differ by 5%

An equiavalent expression for 40+36 can be:
46+30
50+26
etc.
As long as the expression equals 76, it is correct
hope this helps
