High school tried to determine the mean amount of money that each student had saved. The study surveyed a random sample of 66 students in the high
school and found a mean savings of 3500 dollars with a standard deviation of 500

nearest whole number.

Suppose that f(0) = −3 and f '(x) ≤ 8 for all values of x. how large can f(4) possibly be? solution we are given that f is differentiable (and therefore continuous) everywhere. in particular, we can apply the mean value theorem on the interval [0, 4] . there exists a number c such that
