Bob and Mary Kay have gross household income of $7,000 per month. They both have great credit scores and the home they are interested in buying appraised higher than the selling price. They have combined monthly debt payments of $300 in student loans, $650 in car loans, and they pay their credit cards in full every month. The PITI on the new home will be $1,800 per month. Before they pay the $250 loan application fee, they are asking you for your opinion on whether they will get approved for a mortgage. What will you advise them

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
