Answer:
3
Step-by-step explanation:
Define the range of a list of numbers.
<em>I'm not %100 percent certain because I learned that a long time ago.</em>
Answer:
Standard deviation of the students = 0.408
The students would you have to poll to be 95% confident of the outcome within /- 2% of the vote
= 0.408 X 1600
= 652.8
Step-by-step explanation:
<u><em>Step(i):</em></u>-
Given sample size 'n' = 1600
95% confidence interval of the margin error is determined by

Level of significance = 0.05
Z₀.₀₅ = 1.96
Given Margin of error = 2% = 0.02


0.02 X √1600 = 1.96 X S.D

Standard deviation of the students = 0.408
The students would you have to poll to be 95% confident of the outcome within /- 2% of the vote
= 0.408 X 1600
= 652.8
A,C,D those were the answers i put and they were correct.

Answer:
1. 16π
2. 112π
3. 351.68
Step-by-step explanation:
Area of a circle = πr^2
Substitute...
=4^2π
=16π
To find the how much fluid it can hold, just basically find its volume. To do that, you mutiply the area of the base by the height. So...
16π*7=122π
You then just subsitute π by 3.14 so...
122(3.14)=351.68
