Niles and Marsha adopted an infant boy (a U. S. citizen). They paid $17,000 in 2019 for adoption-related expenses. The adoption was finalized in early 2020. Marsha received $3,500 of employer-provided adoption benefits. For question (a), assume that any adoption credit is not limited by modified AGI or by the amount of tax liability. Required: What amount of adoption credit, if any, can Niles and Marsha take in 2020

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
