Daniel wants to buy a laptop computer, and he has $300 in savings. he can purchase a new computer for $279 or a refurbished [repaired or renovated] computer for $100. what should daniel do next? a. evaluate his decision to buy a computer. b. revise his budget to allow for a new computer. c. obtain a credit card to pay for a refurbished computer .d. review the pros ad cons of the different available computers.

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
