How do communism and socialism differ in terms of the role that government plays in the economy ?

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

Identify whether the statements are true or false by dragging and dropping the appropriate term into the bin provided. long-run economic growth is unlikely to be sustainable because of finite natural resources. in the modern economy, countries that possess few domestic natural resources essentially have no chance to develop economically. finding alternatives to natural resources will be very important to long-term economic growth. in the modern economy, human and physical capital are generally less important in productivity than natural resources. in the 19th century, countries with the highest per capita gdp were nearly always abundant in minerals and productive farming land.
