Margaret and David Simmons are married and file a joint income tax return. They have two dependent children, Margo, 5 years old (Social Security number 316-31-4890), and Daniel, who was born during the year (Social Security number 316-31-7894). Margaret's wages are $3,000, and David has wages of $14,000. In addition, they receive interest income of $200 during the year. Margaret and David do not have any other items of income and do not have any deductions for adjusted gross income. Assuming the Simmons file Form 1040A for 2017, complete Schedule EIC and the Earned Income Credit Worksheet A, on Pages 6-67 and 6-68. (The EIC table is in Appendix B.)

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
