Answer:
Step-by-step explanation:
I would write an inequality at this point
The variable would be the amount of hours(x) it would take for the costs to tip the scales
9.75x-10≥7.25x
-10≥-2.5x
4≥x
It would take them 4 hours for the costs to be equal, so anything higher than this would work
<em>Answer</em>
68.4%
<em>Step-by-step explanation</em>
The volume of a cylinder is calculated as follows:

where <em>r </em>is the radius and <em>h </em>is the height of the cylinder.
In the case of cylinder A, its radius is r = 5 ft (= 10/2) and its height is h = 14 ft. Then, its volume is:

In the case of cylinder B, its radius is r = 8 ft (= 16/2) and its height is h = 8 ft. Then, its volume is:

After the pumping is completed all the liquid in cylinder A, which was full, is placed in cylinder B. If the volume of cylinder B represents 100%, then we need to find what percent, <em>x</em>, represents the volume of cylinder A. We can do this with the help of the next proportion:

Solving for x:
Good lesson and good day ^-^
Answer:
8/3
Step-by-step explanation:
Given:
value of the test statistic is t20 = 1.95
corresponding p-value of 0.0653 at the 5% significance level
No, I can't conclude that the correlation coefficient differs from zero because the p-value, which is 0.0653 exceeds 0.05.
The correlation coefficient differs from zero when the p-value is less than 0.05.
