Male and female high school students reported how many hours they worked each week in summer jobs. the data is represented in the following box plots: two box plots shown. the top one is labeled males. minimum at 1, q1 at 3, median at 10.5, q3 at 14, maximum at 21. the bottom box plot is labeled females. minimum at 0, q1 at 15, median at 18, q3 at 21, no maximum shown identify any values of data that might affect the statistical measures of spread and center.

Consider the set of all four-digit positive integers less than 2000 whose digits have a sum of 24. what is the median of this set of integers?

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.

Money off coupons have been circulated to 300 households. only 2/5 of these were redeemed (used) in the local supermarket to get a free shampoo. what fraction of coupons were unused? (ps: write how you got the answer)
