Please answer question 8-14

unlikely that a trial and error rounded solution will meet room availability limits. This means One way to improve the chances for a successful execution of the integer model is om For example, if the hospital has only two dental surgeons on a given day, no more than two the feasible ranes for the variables by taking into account the availability of other Test rooms (of any type) can be assigned to that department on that day, Setting tighter bounds may be effective in securing an optimal integer solution.

The applications fall into three categories: in-state, out-of-state. and international. The male-female ratios for in-state and out-of-state applicants are 1:1 and 3:2, respectively. For international students, the corresponding ratio is 8:1. The American College Test (ACT) score is an important factor in accepting new students The statistics gathered by the university indicate that the average ACT scores for in-state, out-of-state, and international students are 27,26, and 23, respectively. The committee on admissions has established the following desirable goals for the new freshman class: (a) The incoming class is at least 1200 freshmen. (b) The average ACT score for all incoming students is at least 25. (c) International students constitute at least 10% of the incoming class. important as any of the remaining goals.
