#2
John walks at a speed (miles/hr) that is uniformly distributed on the interval [A,B], where A is uniformly distributed on the interval [0,2] and B is uniformly distributed on the interval [1,3]. The distance between John's apartment and school is 1.5 miles. What is the expected time that Hussein will spend on the road on his way back to his apartment?
Homework Answers
Expected value of A = (0+2)/2 = 1
Expected value of B = (1+3)/2 = 2
So expected interval [A,B] = [ 1,2]
Expected value of speed = (1+2)/2 = 1.5 miles /hr
Expected time = distance / expected speed = 1.5/1.5 = 1 hr

In the above problem, what are the natural places where you
would put the hospital? Why? Now, strengthen your intuition by
determining the expected distance between the random accident point
and the fixed point a where the hospital is located. Find the value
of for which this expectation is minimized. Then look at your
first, intuitive answer. What have you learned?

MANAGERIAL ACCOUNTING CASE STUDY.CASE ASSIGNMENT #1: Cortland Manufacturing, Inc.We constantly seem to be pricing ourselves out of some markets and not charging enough in others. Our pricing policy is pretty simple: we mark up our full manufacturing cost by 50%. That means a computer that costs us $2,000 to manufacture will sell for $3,000. Until now I thought this was a workable approach, but now I’m not so sure.Steve Works, CEO, Cortland Manufacturing, Inc. (CMI)Steve’s Controller, Sally Nomer, had just...

Founded in 2006 by Blake Mycoskie, TOMS Shoes was an American footwear company based in Santa Monica, California. Although TOMS Shoes was a for-profit business, its mission was more like that of a not-for-profit organization. The firm’s reason for existence was to donate to children in need one new pair of shoes for every pair of shoes sold. Blake Mycoskie referred to it as the company’s “One for One” business model. While vacationing in Argentina during 2006, Mycoskie befriended children...
