Oscar has a $2,500 balance on his credit card that accumulates 14.5% interest compounded annually. Which of the following could be used to find the balance on the card after 5 years? A. A = 2500(1 + 0.145)5

A. , A... equals... 2,500... 1 plus 0 point 1 4 5 to the 5th power,

B. A = 2500 × 0.145 × 5

B. , , A equals... 2,500 times 0 point 1 4 5 times 5, ,

C. A = 2500(1 + 0.05)14.5

C. , , A... equals... 2,500 1 plus 0 point 0 5 to the 14 point 5 power, ,

D. A = 0.145(1 + 2500)5

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?
