Jenna just opened a checking account at the bank. within the first month, she deposited three checks for $34.98, $51.02, and $51.22. she withdrew $5.23 for new pencils, $5.22 for cards, and $7.89 for movies from her account in the same month. order the rational numbers from least to greatest and explain your reasoning.

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?
