- Use Big M method to solve the following question. Min 4x1+4x2+x3 s.t. x1+x2+x3≤2 2x1+x2≤3 2x1+x2+3x3≥3 x1,x2,x3≥0arrow_forwardIn a classic study of problem solving, Duncker (1945) asked participants to mount a candle on a wall in an upright position so that it would burn normally. One group was given a candle, a book of matches, and a box of tacks. A second group was given the same items, except that the tacks and the box were presented separately as two distinct items. The solution to this problem involves using the tacks to mount the box on the wall, creating a shelf for the candle. Duncker reasoned that the first group of participants would have trouble seeing a new function for the box (a shelf) because it was already serving a function (holding tacks). For each participant, the amount of time to solve the problem was recorded. Data similar to Duncker’s are as follows. Time to Solve Problem (in sec.)

- Apply the pigeonhole principle to answer the following questions. If the pigeonhole principle cannot be applied, give a specific counterexample. 1. A team of three high jumpers all have a personal record that is at least 6 feet and less than 7 feet. Is it necessarily true that two of the team members must have personal records that are within four inches of each other? 2. What if there are four jumpers? Note that here heights are measured to within a precision of 1/4 incharrow_forwardSubmitting this question again as the previous solution was incorrectarrow_forward1.
