In this problem,
and 
Finding the derivative of each gives us the following:


Plugging these values into the product rule gives us the final derivative:

You have to do the math right to get this right. so just add then multiply add them the subtract
Okay, for variable B you have the data points:
1, 2, 3, 5, 6, 6, 7, 7, 10, and 10.
What you need to do to find the mean (or average) is add all the data up and divide by how many pieces of data you had. So, the sum of all the points is 57. There are 10 points overall.
57/10 is 5.7
Your average for variable B is 5.7
