In a market economy, competition is a crucial requirement. What is one benefit to fostering competition in an economic system? It gives consumers more choices in the quality and price for things they want to buy.
It causes higher prices, so businesses make a higher amount of profits.
It limits the freedom companies have to create new products.
It never requires any outside assistance from the government.

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
