Iliana cubed the number of flowering plants in her garden, then added 2 vegetable plants. let p represent the original number of plants in her garden. which shows an expression to represent the total number of plants in her garden and the total number of plants if p = 3?
a. 3p - 2 when p = 3 the number of plants is 7
b. 3p + 2 when p = 3 the number of plants is 11
c. p^3 - 2 when p = 3 the number of plants is 25
d. p^3 + 2when p = 3 the number of plants is 29

Acable car begins its trip by moving up a hill. as it moves up, it gains elevation at a constant rate of 50 feet/minute until it reaches the peak at 2,000 feet. then, as the car moves down to the hill’s base, its elevation drops at the same rate.

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?

Let event a = you roll an even number on the first cube. let event b = you roll a 6 on the second cube. are the events independent or dependent? why?
