Consider the function represented by the equation 69 = 38 - 9. Write the equation in function notation, where q is the independent variable.
o f(q) = 1/29 - 02/26
f(q) = 2s + 3
O f15) = {s - Ž
Of(q) = 29 + 3

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?
