Consider the sequence of steps to solve the equation: x-3/3=x+3 step 1 ⇒ x - 3 = 3(x + 3) step 2 ⇒ x - 3 = 3x + 9 step 3 ⇒ x = 3x + 12 step 4 ⇒ -2x = 12 step 5 ⇒ x = -6 identify the property of equality which yields step 1. a) division property b) addition property c) subtraction property d) multiplication property

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?
