Answer:
104.7 in^3
Step-by-step explanation:
Step one:
given data
The ball has a radius of 5 inches and
the cylinder has a height of 8 inches
Step two:
The volume of the cylinder

substitute our data

The volume of the ball

substitute our data

The space will have a volume of
=628.4-523.7
=104.7 in^3
Answer:
b. 2.333
Step-by-step explanation:
Test if the mean transaction time exceeds 60 seconds.
At the null hypothesis, we test if the mean transaction time is of 60 seconds, that is:

At the alternate hypothesis, we test if it exceeds, that is:

The test statistic is:

In which X is the sample mean,
is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.
60 is tested at the null hypothesis:
This means that 
A sample of 16 ATM transactions shows a mean transaction time of 67 seconds with a standard deviation of 12 seconds.
This means that 
Value of the test statistic:




Thus, the correct answer is given by option b.
circumference of the tire = 37 x Pi = 116.24 inches
1 mile = 5280 feet = 63360 inches
63360/116.24 = 545.08 revolutions per mile
545.08 x 5 = 2725.4 revolutions in 5 miles
Round answer as needed.
Answer:
There would be 2 answers because it is a quadratic equation
x=4 or x=8
It’s B, because you do 3-15 and that equals 12 and then you do 3 divided by 12 and that’s 4.
