The sequence below shows the number of bacteria Arjun observed each hour for a science experiment: 5, 20, 80, 320,1,280,... Which recursive function describes the number of bacteria observed at the nth hour? f(1) = 5 f(n+1) = 2f(n) + 10, f(1) = 1 f(n+1) = 5f(n), f(1) =1 f(n+1) = 4f(n), or f(1) = 5 f(n + 1) = 4f(n)

Which graph represents an even function?

Wrote and expression for the difference of p and 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?
