7. Use R to answer the following question. Copy and paste the code and answer from R into your paper. In a class of 100 students, 25 have hardcover and 75 students have paperback textbooks. If you randomly choose 15 students in this class, find the probability that 3 of them have hardcover texts.

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
