Answer: 1356 cubic feet
Step-by-step explanation:
The volume of cylinder is given by :_
, where r is the radius and l is the length of the cylinder.
Given : A cylindrical diesel fuel holding tank has a radius of r= 6 feet and a length of l=12 feet.
Therefore,
Hence, the volume of cylindrical diesel fuel holding tank =1356 cubic feet
Therefore, the maximum volume of fuel the tank can hold 1356 cubic feet.
Answer:
a)At the 10% significance level, we fail to reject the null hypothesis.
b) P-value is ≈ 0.48
Step-by-step explanation:
Let p be the proportion of the auditors agree with the statement "Cash flow is an important indicator of profitability."
Then,
: p=0.5
: p≠0.5
Test statistic can be calculated as:
z= where
Using these numbers we get:
z=≈0,707
and p(z) is ≈ 0.48. Since 0.48>0.10, the result is not significant at 90% level. Therefore we fail to reject the null hypothesis.
