Paul and Lois Lee, both age 53, are married and will file a joint return for 2018. Their 2018 adjusted gross income is expected to be $85,000, including Paul's $75,000 salary. Lois has no income of her own. Neither spouse is covered by an employer-sponsored pension plan. What amount can the Lees contribute to IRAs for 2018 to take advantage of their maximum allowable IRA deduction in their 2018 return

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
