The front of a roller-coaster is at the bottom of a hill and is 15 feet above the ground. If the front of the roller-coaster rises at a constant rate of 8 feet per second, which of the following equations gives the height, h, in feet, of the front of the roller-coaster car s seconds after it starts up the hill?

• h = 8s + 335/15

• h = 15s + 8

• h = 15s + 335/8

• h = 8s + 15

The formula E = (O + 4M + P)/6 is often used by project managers to compute E, the estimated time to complete a job, where O is the shortest completion time, P is the longest completion time, and M is the most likely completion time. Which of the following correctly gives P in terms of E, O, and M?

• P = (O + 4M - E)/6

• P = -6E + O + 4M

• P = 6E - O - 4M

• P = (O + 4M + E)/6
