They set up a table on campus and wait for students to come and purchasetheir cookies. Consider the following variables in this bake sale operation:1. Size of the cookies2. Weather conditions on campus3. Organization of the table4. Number of cookies sold5. Competition from other fund-raisers coinciding on campus6. Amount of advertising and shouting of the students at the bake sale table7. Number of students on campus that dayWhich of these variables are input variables?a. 1 and 2b. 1 and 3c. 1, 3, and 5d. 1, 3, and 6
- TRUE OR FALSE The simplex method is a linear programming procedure designed to handle only three variablesA hotel has 200 rooms and 2 fares: low fare, which is $250 per night’s stay, and high fare, which is $350 per night’s stay. The low fare is for leisure travelers who will book first, and the high fare is for business travelers who will book after all leisure travelers have made their booking. Suppose that there are a sufficiently large number of leisure travelers, which means that every room except rooms kept for business travelers will be booked by leisure travelers. If a low-fare room is booked, the hotel will spend $14 in hiring a part-time employee to clean the room ($14/room); if a high-fare room is booked, the hotel will spend $25 in hiring a part-time employee to clean the room thoroughly ($25/room). For both types of rooms, if they are booked, the hotel has to pay $10/room for the consumption of electricity and water. The number of business travelers who want to book a room is discrete uniformly distributed over 41, 42, …, 50. Please find out the optimal protection level for…True or False. A variable's slack value is the amount below the minimum or beyond the maximum for that constraint.
- 2FRUIT COMPUTER COMPANY Fruit Computer Company manufactures memory chips in batches of ten chips. From past experience, Fruit knows that 80% of all batches contain 10% (1 out of 10) defective chips, and 20% of all batches contain 50% (5 out of 10) defective chips. If a good (that is, 10% defective) batch of chips is sent to the next stage of production, processing costs of $4000 are incurred, and if a bad batch (50% defective) is sent on to the next stage of production, processing costs of $16000 are incurred. Fruit also has the alternative of reworking a batch at a cost of $4000. A reworked batch is sure to be a good batch. Alternatively, for a cost of $400, Fruit can test one chip from each batch in an attempt to determine whether the batch is defective. QUESTIONS 1.Determine a strategy so Fruit can minimize the expected total cost per batch. 2.Compute the EVSI and EVPI.The Decision Sciences Department is tyring to determine whether to rent a slow or fast copier. The department believes that an employee's time is worth $15/hour. The slow copier rents for $4/hr, and it takes an employee an average of 10 minutes to complete copying. The fast copier rents for $15/hr, and it takes an employee an average of 6 minutes to complete copying. On average, four employees per hour need to use the copying machine. (Assume the copying times and interarrival times to the copying machine are exponentially distributed.) Which machine should the department rent to minimize expected total cost per hour? Please note this class revolves around Microsoft Excel so the answer I need needs to show the formulas in Excel, along with any corresponding graphs, etc. Thank you in advance!
