Before the last school year began, it was estimated that the average discretionary personal expenses each school year for a student attending a 4-year public college were $2,110. this past summer ashley decided to poll seven of her friends attending a 4-year public college because she thought that estimate was low. she made a list of their actual school-year expenses: $2,800, $1,990, $2,005, $2,400, $1,860, $2,200, $2,000 what is the mean of her friends' personal expenses? round your answer to the nearest cent. is the average higher or lower than the estimate? what would ashley's actual personal expenses for that school year have to be so that her amount and her friends' amounts together would have an average of $2,110?

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

there are no choices to this, can you give us some choices so that i can answer it
