Why entrepreneurs start businesses. a) monopolistic competition b) perfect competition c) sole proprietorship d) profit motive

As sales exceed the break‑even point, a high contribution‑margin percentage (a) increases profits faster than does a low contribution-margin percentage (b) increases profits at the same rate as a low contribution-margin percentage (c) decreases profits at the same rate as a low contribution-margin percentage (d) increases profits slower than does a low contribution-margin percentage

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
