the area of a rectangular raised garden bed for growing beets is given by the expression(3b)(3b-3). the length, l, of the mat is greater than its width, w.

based on the given information and the formula for area of a rectangle a=∫w, , which of the following statements must be true?

a
the coefficient of b is 3, meaning the length of the rectangle is three times its width.

b
(3b-3) is a factor in the expression and represents the length of the rectangle.

c
(3b-3) is a term in the expression and represents the width of the rectangle.

d
the term -3 means that the width of the rectangle is 3 units less than its length.

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?

Someone answer this asap for the first five terms of a sequence are shown. 5, 11, 23, 47, 95, . . which recursive function defines the nth term in the sequence for n > 1? a. f(n) = f(n - 1) + 6 b) f(n) = f(n - 1) + 48 c) f(n) = 3 • f(n - 1) + 1 d) f(n) = 3 • f(n - 1) - 4
