What are some key ways in which government spending and tax expenditures differ? Select all that apply. They differ in that government spending explicitly subtracts from the federal budget, whereas tax expenditures reduce the tax revenue available for government spending. tax expenditures disproportionately benefit the poor, whereas government spending is more helpful to the wealthy. tax expenditures allow people to keep their hard‑earned income, whereas government spending takes it from them. government spending must be renewed or evaluated each year, whereas tax expenditures renew automatically.

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
