Answer:
What is the volume of this shape? 256π units³
Step-by-step explanation:
= π × r² × h
= π × 8 × 8 × 4
= 256π units³
The sample size is, 9604 if you want to obtain a sample to estimate a population proportion at this point in time, you have no reasonable estimate for the population proportion.
<h3>What is the margin of error(MOE)?</h3>
It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.
As we know, the sample size can be evaluated using the expression:
or
Here ME = 1% = 0.01
p = 0.5, q = 0.5
Z at α 0.05 (because 95% confident)
= 1.960
n = 9604
Thus, the sample size is, 9604 if you want to obtain a sample to estimate a population proportion at this point in time, you have no reasonable estimate for the population proportion.

If you have 14 coins in your pocket and the amount of money you have in your pocket is 2.50, when only using nickels and quarters you would have:
5 Nickels=0.25
9 Quarters=2.25
0.25+2.25=$2.50 (money)
9+5= 14 (amount of coins)
So you would have 5 nickeled and 9 quarters.
