Clayton transferred a balance of $4125 to a new credit card at the beginning
of the year. The card offered an introductory APR of 7.9% for the first 5
months and a standard APR of 25.7% thereafter. If the card compounds
interest monthly, which of these expressions represents Clayton's balance at
the end of the year? (Assume that Clayton will make no payments or new
purchases during the year, and ignore any possible late payment fees.)

What are the solutions of the equation? 5z^2 + 9z - 2 = 0 a. 1, -2 b. 1, 2 c. 1/5, -2 d. 1/5, 2

Reduce fractions expressing probability to lowest terms. in 3,000 repetitions of an experiment, a random event occurred in 500 cases. the expected probability of this event is?

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?
