Assume the annual day care cost per child is normally distributed with a mean of $8000 and a standard deviation of $1000. In a random sample of 250 families, how many pay more than $6910 annually for day care per child?

How do you answer this question? (step by step)

The table represents a linear function. what is the slope of the function? –6 –4 4 6

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
