Answer: C. There is sufficient evidence to support the claim .
Step-by-step explanation:
Given (claim) :The mean monthly gasoline bill for one household is greater than $140.
Let 
be the population mean.
Then, the set of hypothesis for this claim will be:-
If a hypothesis test is performed , then to interpret a decision that fails to reject the null hypothesis we says that there is sufficient evidence to support the claim
Answer:
4.5
Step-by-step explanation:
Answer:
4pi in^2
Step-by-step explanation:
Lateral surface area of a cylinder = 2πrh
π = pi
r = radius
h = height
Let me illustrate with an example
A cylinder has the following dimensions
r = radius = 20
h = height = 10
lateral area = 2 x π x 20 x 10 = 400π
If dimensions are reduced to one-fifth their original length, new dimensions are
r = radius = 20 x 1/5 = 4
h = height = 10 x 1/5 = 2
New lateral area = 2 x 4 x 2 x π = 16π
change in lateral area = 400π / 16π = 25
If dimensions are reduced by 1/5, lateral area would reduce by 25
100 pi / 25 = 4
For the first bit, put $930 + 7.5x and the second part is 58,000, 930 x 7.5 x 8
