Divide one into fouth equal peices and one into eight equal peices.
Color 3 peices into the 4 peice shape
Color 6 peices into the 8 peice shape.

Answer:
The 99% confidence interval estimate of the proportion of people who say that they voted is (0.6623, 0.7369).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .
In a survey of 1002 people, 701 said that they voted in a recent presidential election.
This means that
99% confidence level
So , z is the value of Z that has a p-value of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 99% confidence interval estimate of the proportion of people who say that they voted is (0.6623, 0.7369).
The maximum length of PQ = The Diameter of first sphere + the diameter of second sphere = 2×7 + 2×4 = 14 + 8 = 22 ;
Answer:
yes
Step-by-step explanation:
The numbers satisfy the Pythagorean theorem:
53^2 = 28^2 +45^2
2809 = 784 +2025
(28, 45, 53) is a Pythagorean triple. These lengths will make a right triangle.
