Abaseball stadium holds 15,002 seats. the lower level has 50 fewer than three times as many seats as the upper
level. the middle level has 40 more than twice as many seats as the upper level. let x represent the number of
upper-level seats
which equation represents this scenario?
x + (2x + 20) + (3x – 50) = 15,002
x+ (2x + 40) + (3x – 50) = 15,002
x + 2(20 + x) + 3(50 – x) = 15,002
x + 2(x + 20) + 3(x - 50) = 15,002

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?
