10. The Westchester County Superintendent of Education is responsible for assigning students to the three magnet high schools in her county. She recognizes the need to bus a certain number of students, for several sectors of the county are beyond walking distance to a magnet school. The superintendent partitions the county into five geographic sectors as she attempts to establish a plan that will minimize the total number of student miles traveled by bus. She also recognizes that if a student happens to live in a certain sector and is assigned to the magnet high school in that sector, there is no need to bus him/her since he/she can walk to school. The three magnet schools are located in sectors B, C, and E. The accompanying table reflects the number of magnet high-school-age students living in each sector and the distance in miles from each sector to each school. Each Magnet High School has a capacity of 900 students. Set up the objective function and constraints of this problem, and solve using MS Excel. this question was answered need solver help

Shown below are rental and leasing revenue figures for office machinery and equipment in the United States over a 7-year period according to the U.S. Census Bureau. Use this data and the regression tool in the data analysis tool pack to run a linear regression. Based on the formula you get from the regression output, answer the following questions: a) What is the forecast for the rental and leasing revenue for the year 2011? b) How confident are you in this forecast? Explain your answer by citing the relevant metrics. Year Rental and Leasing ($ millions) 2004 5,860 2005 6,632 2006 6,543 2007 5,952 2008 5,732 2009 5,423 2010 4,589

Which of the following statements are true? Check all that apply.
In a total conflict game, there can be more than one saddle point.
"Equating the expected values" method can be applied for any 2x2 total conflict game.
When the maximin and minimax values in a total conflict game are same, there is no pure strategy.
"Method of Oddments" can be used for 2x2 total conflict game only if there is no saddle point in pure strategies.
If there are two saddle points in a total conflict game, the two have the same value.

During a voyage of the old Bass Strait ferry, The Abel Tasman, the Rip at the entrance to Port Phillip Bay caused the navigator some concern. He needed to sail due north, but the current was flowing northwest at 10 km/h. In still water, the Abel Tasman has a maximum speed of 25 km/h. Find the following:
(a) the actual direction of travel if he had simply pointed the boat towards North.
(b) the course necessary to travel in the required direction.
(c) the ship’s velocity relative to Point Lonsdale (a fixed point on land).
