Answer:
The 95% confidence interval estimate of the proportion of people who say that they voted
(0.67122 , 0.72798)
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
In a recent survey of 1002 people, 701 said that they voted in a recent presidential election.
Sample proportion
<u><em>Step(ii)</em></u>
The 95% confidence interval estimate of the proportion of people who say that they voted
(0.6996 - 1.96 X 0.01448 , 0.6996 + 1.96 X 0.01448)
(0.6996 - 0.02838 , 0.6996 + 0.02838)
(0.67122 , 0.72798)
<u><em>Final answer</em></u>:-
The 95% confidence interval estimate of the proportion of people who say that they voted
(0.67122 , 0.72798)
AnswThe method is to separate the variable from everything else. That means getting the variable on one side of the equals sign and everything else on the other side. A=5B+8.
Subtract 8 from each side: A-8=5B.
Now divide each side by 5: (A-8)/5=B.
So B=(A-8)/5.

Answer:
411.38
Step-by-step explanation:
When you add 27.38 and 384 together, you get 411.38.
Answer:
The radius of a hexagon is called the apothem, which in this case is 15.
We need to know the side length which is found by the equation:
side length = apothem * 2 * (tan (180 / #sides))
side length = apothem * 2 * (tan (180 / 6))
side length = 15 * 2 * (tan (30 degrees))
side length = 30 * .57735
side length = 17.3205
We need the perimeter of the hexagon which equals the side length times six.
perimeter = 6 * 17.3205 = 103.923
