(MULTIPLE PARTS OFFERING A LOT OF POINTS) What is the frequency of the wave pictured in the graph above? What is the bit depth of the graph? What is the sample rate of the graph?

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?

Y=21.95x+10 y=22.45x solve by substitution

X² + 4y² = 36 the major axis runs along: a) y=4x b) x-axis c) y-axis
