Problem Two pumps capable of delivering 100hp to an agricultural farm are being evaluated in a present economy study. The selected pump will only be utilized for one year, and it will have no market value at the end of the year. The data are as follows: If electric power costs 10/kWh and the pump will be operated 4,000hrs per year, which pump should be chosen? Recall that 1hp=746 Watts. Problem Two pumps capable of delivering 100hp to an agricultural farm are being evaluated in a present economy study. The selected pump will only be utilized for four years, and it will have no market value at the end of the vear. The data are as follows: If electric power costs 10k/kWh and the pump will be operated 1,000hrs per year, and the discount rate is 7% which pump should be chosen? About decision tree ( not all data of the problem are written here, at least know the idea): Aysha has finished school and she has two choices to complete her high education either at SQU or at Dofar University. In both universities either she study Engineering or Business. When she completes her study at one of them either she graduates or not graduate, The following are given : 1- If she study at SQU engineering, the probability of graduating is 0.6 (probability not graduating =0.4 ). 2- If she study at SQU business, the probability of graduating is 0.7 (probability not graduating =0.3 ). 3- If she study at Dofar engineering, the probability of graduating is 0.8 (probability not graduating =0.2 ). 4- If she study at Dofar business, the probability of graduating is 0.9 (probability not graduating =0.4 ). 5- Also there are money givens (Not written I don't remember them L ). That numbers represent the earns from each major in both colleges. Develop a decision tree and determine in which university she has to study and in which major.
