Answer:

Step-by-step explanation:
We are given that a function

We have to find the average value of function on the given interval [0,7]
Average value of function on interval [a,b] is given by

Using the formula

![f_{avg}=\frac{1}{7}[e^{\frac{x}{7}}\times 7)]^{7}_{0}](https://tex.z-dn.net/?f=f_%7Bavg%7D%3D%5Cfrac%7B1%7D%7B7%7D%5Be%5E%7B%5Cfrac%7Bx%7D%7B7%7D%7D%5Ctimes%207%29%5D%5E%7B7%7D_%7B0%7D)
By using the formula


Because 

Hence, the average value of function on interval [0,7]

So yuo simplyfly
15:20=3:4
6:8=3:4
8:12=2:3
9:12=3:4
so your answer is not c
Answer:
26.5%
Step-by-step explanation:
<u>Increasing Percentages</u>
When sequential percentages increasing are computed, each increase applies to the previous result, instead of the first quantity. That is why sometimes the final results may be confusing. For example, increasing 10% and then 15% will not be the same as increasing a total of 25%.
The average test scores of RSM students first increased by 10%. It means that some quantity C increased by

Now the average test scores are

A new increasing occurred by 15%, and the previous quantity must be multiplied by 1.15, so the final average test scores are

It means that the total increasing was

The answer to this would be A.
This is because the numerators represent the the number of tomatoes and the denominators represent the amount of pints that are being made. The fraction on each side of the equal sign compares the number of tomatoes to the amount of pints. Therefore, the correct answer would be A. Hope I helped :)
