The illustration below shows the graph of y as a function of 2. Complete the following sentences based on the graph of the function.
(Enter the s-intercepts from least to greatest.)
• This is the graph of a
V
function.
• The y-intercept of the graph is the function value y =
• The -intercepts of the graph (in order from least to greatest) are located at 2 =
and 2 =
and it occurs when =
• The greatest value of y is y =
0.

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?
