A student used the point-slope form to write the 3
equation of a line that has a slope of and passes
through the point (3,-2). The student's work is shown
to the left.
Step 1:y-(-2) = (x-3)
Step 2: y+2=*-
Step 3: y+2+2=2x-23
Step 4: y=x-4

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?
