Sallie bought snacks to take on a trip. She bought 6 red jellos, 8 chocolate puddings,
12 granola bars, and 12 cookie packs. If
she randomly chooses a snack, and then
puts it back and randomly chooses a
second snack, what is the probability that
she will choose a red jello and cookie
pack?

Determine whether the set of whole numbers is closed under addition. explain why the set is or is not closed. give an example.

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.

Which expression is equivalent to -12(3x-3/4)
