Which quadratic function, when graphed, has x-intercepts of -10 and 6? A Oy= (10.2 - 6) (6x + 10)
B. Oy= (1 - 10) (+6)
cOy=(1 - 10x) (6x +1)
DOy = (a + 10) (23 – 12)

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?
