Sione has some questions: "After the translation, what is the scale factor for the enlargement that carries circle A onto circle B? And, what is the scale factor for the reduction that carries circle B onto circle A? fonto .B -2 rl R 1) How would you answer Sione's questions?

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?
