The function h(x)=1/2(x+3)^2+2. how is the graph of h(x) translated from the parent graph of a quadratic function, f(x)=x^2? select all that apply. a. the graph of h(x) is shifted 3 units to the right of the parent graph. b. the graph of h(x) is shifted 2 units up from the parent graph. c. the graph of h(x) is vertically compressed by a factor of 1/2 d. the graph of h(x) is a reflection of the parent graph. e. the graph of h(x) has a different y-intercept from the parent graph. f. both graphs have two x intercepts.

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?
