The law of diminishing marginal utility explains why

1. supply curves slope upward.
2. demand curves slope downward.
3. addicts can never get enough.
4. people will only consume their favorite goods and not try new things.

Your father's employer was just acquired, and he was given a severance payment of $375,000, which he invested at a 7.5% annual rate. he now plans to retire, and he wants to withdraw $35,000 at the end of each year, starting at the end of this year. how many years will it take to exhaust his funds, i. e., run the account down to zero? a. 22.50 b. 23.63 c. 24.81 d. 26.05 e. 27.35

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
