Susan has at most $90 to spend at the store to get ready for her party. She wants to buy deli meat that costs $10 per pound and fancy bread that costs $9 per loaf. However, she can only hold at most 6 items in her basket. How many pounds of deli meat and loaves of bread should she buy? Write a system of inequalities to model the situation. Let x represent number of pounds of deli meat and let y represent number of loafs of bread. What is on of the inequalities from this situation above?

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?
