636.17251
Step-by-step explanation:
V = πr^2h = π·4.5^2·10 ≈ 636.17251
Answer:
A sample size of 35 is needed.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the width W as such
In which 
is the standard deviation of the population and n is the size of the sample.
How large must the sample size be if the width of the 95% interval for mu is to be 1.0:
We need to find n for which W = 1.
We have that 
, then 
. So
Rounding up
A sample size of 35 is needed.
Answer: The answer would be a line that is not as steep and a reflection in the line y = x.
If the a value in the equation is greater than 1, we will have a line that is steeper than the line y = x.
Now, we we take the inverse of the line, it will have a slope that is lower than y = x.
The graphs will be reflected in the line y = x.
Try graphing y = 3x and 3y = x.
Decimal: .32
fraction: 32/100 which, when reduced, is 8/25
