Answer: 1.9 inches
Step-by-step explanation:
- the equation to find the volume of a cylinder is V = π r^2 h
- so we can just change this equation around to H = V / π r^2
- so H = 384/ π 8^2 = 1.91 or 1.9
hope this helps :)
Answer:
at least $1,050,000
Step-by-step explanation:
Deandre's salary will be ...
12000 + 0.06·sales
He wants that to be at least 75000, so the sales must meet the requirement ...
12000 + 0.06·sales ≥ 75000
0.06·sales ≥ 63000 . . . . . . . . . . . . subtract 12000
sales ≥ 63000/0.06 . . . . . . . . . . . .divide by 0.06
sales ≥ 1,050,000 . . . . . . . . . . . . . .evaluate
He will need to have at least $1,050,000 in total sales to have a yearly income at least $75,000.

Answer:
There is no statistical evidence to support the claim that the mean is elss than 74.
Step-by-step explanation:
Given that a paint-drying situation in which drying time for a test specimen is normally distributed with s = 6.
The hypotheses H0: µ = 74 and Ha: µ < 74
are to be tested using a random sample of n = 25 observations
a) Z = 
ie. -1.417 std deviations to the left of mean.
b) p value = 0.078241
Since p > 0.01 , our alpha, accept H0
There is no statistical evidence to support the claim that the mean is elss than 74.
