Given a cost function C(x) as
C(x)=20+x−(1/2)x^2,
calculate the marginal average cost when x=2, use this to approximate the average cost when x=3, and calculate the percentage error between this estimate and the actual cost when x=3. Give your answer as a percentage to the nearest integer. Do not include the percent symbol in your answer.

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?
