Suppose you want just guess at the answers in a 5 question multiple-choice test. each question has 3 responses and only one is correct. what is the probability of getting two questions right just guessing? 20 points 0.3275 0.2753 0.7532 none of the above

Plot the points (0,6), (3,15.8), and (9.5,0) using the graphing tool, and find the function

How can you tell when x and y are not directly proportional?
