Abcd is a quadrilateral inscribed in a circle, as shown below: circle o is shown with a quadrilateral abcd inscribed inside it. angle a is labeled x plus 16. angle b is labeled x degrees. angle c is labeled 6x minus 4. angle d is labeled 2x plus 16. what equation can be used to solve for angle c? (x + 16) + (x) = 180 (x + 16) + (6x β 4) = 180 (x + 16) β (2x + 16) = 180 (x + 16) + (x) = 90

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?
