Lesson 6.11: Bob earns $60,000 a year at an accounting firm. Each year, he receives a raise. Bob
has determined that the probability that he receives a 10% raise is 0.7, the probability that he earns
a 3% raise is 0.2, and the probability that he earns a 2% raise is 0.1.
A competing company has offered Bob a similar position for $65,000 a year. Bob wonders if he
should take the new job or take his chances with his current job. SHOW ALL WORK!
A) Find the mathematical expectation of the dollar amount of his raise at his current job.
B) Based only on the
mathematical expectation found (monetary earnings), should Bob stay at his
current job or accept the new job? Explain your reasoning.

At a sand and gravel plant, sand is falling off a conveyor and onto a conical pile at a rate of 16 cubic feet per minute. the diameter of the base of the cone is approximately three times the altitude. at what rate is the height of the pile changing when the pile is 12 feet high? (hint: the formula for the volume of a cone is v = 1 3 πr2h.)
