George is taking sociology and economics and is preparing for exams in both classes. For economics, he is self-testing on economic problems, which take him 12 minutes each. For sociology, he is rewriting notes, which takes 6 minutes per page. George is considering two study schedules. For the first, he will self-test on 6 economics problems and rewrite 12 pages of sociology notes. For the second, he will self-test on 10 economics problems and rewrite 4 pages of sociology notes. Either schedule will use all of the time he has allotted for studying. 1. How much total time does George plan to spend studying? (answered in minutes)
2. Draw a graph below and mark the two schedules George is considering, and then graph his entire study budget (running from axis to axis).

Consider two similar industries, portal crane manufacturing (pcm) and forklift manufacturing (flm). the pcm industry has exactly three incumbents with annual sales of $800 million, $200 million and $100 million, respectively. the flm industry has also exactly three incumbents, with annual sales of $500 million, $450 million and $400 million, respectively. which industry is more likely to experience a higher level of rivalry?

Aproduction line has three machines a, b, and c, with reliabilities of .96, .86, and .85, respectively. the machines are arranged so that if one breaks down, the others must shut down. engineers are weighing two alternative designs for increasing the line’s reliability. plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. in either case, three machines (a, b, and c) would be used with reliabilities equal to the original three. a. compute overall system reliability under plan 1. (round your intermediate calculations and final answer to 4 decimal places.) reliability b. compute overall system reliability under plan 2. (round your intermediate calculations and final answer to 4 decimal places.) reliability c. which plan will provide the higher reliability? plan2plan1

When randy, a general manager of a national retailer, moved to a different store in his company that was having difficulty, he knew that sales were low and after talking to his employees, he found morale was also low. at first randy thought attitudes were poor due to low sales, but after working closely with employees, he realized that the poor attitudes were actually the cause of poor sales. randy was able to discover the cause of the problem by utilizing skills.
