A rectangular shaped house sits on a rectangular lot. The house is 58 feet by 28 feet, and the lot is (x + 2) feet in width by (2x + 3) feet in length. If the lot is covered with grass, write a polynomial that shows how many square
feet of grass there is to cut.
58 ft
28 ft
(x + 2) ft
(2x + 3) ft

What is the expression in factored form? -x^2 + 3x + 28 a. (x-7)(x-4) b. -(x-7)(x+4) c. (x+4)(x+7) d. -(x-4)(x+7)

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?
