Except for the very first unit sold, the marginal revenue in a monopoly market is always less than the price because the: multiple choice price effect always works in the opposite direction of the marginal effect. price effect always works in the same direction of the quantity effect. price effect always works in the opposite direction of the quantity effect. marginal effect always works in the opposite direction of the quantity effect.

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
