Study the steps used to slove the equation. Given: c/2 - 5 = 7 + 5 Step 1: c/2 - 5 + 5 = 7 + 5
Step 2: c/2 + 0 = 12
Step 3: c/2 = 12
Step 4: 2(c/2) = 12(2)
Step 5: c=24

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?
