A programmer plans to develop a new software system. In planning for the operating system that he will use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be 99% confident that his estimate is in error by no more than four percentage points question mark Complete parts (a) through (c) below. a) Assume that nothing is known about the percentage of computers with new operating systems. equals nothing (Round up to the nearest integer.) b) Assume that a recent survey suggests that about 88% of computers use a new operating system. equals nothing (Round up to the nearest integer.) c) Does the additional survey information from part (b) have much of an effect on the sample size that is required

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.
