Suppose ibm decided to issue commercial paper in denominations of $5,000 to raise a large sum of money. since the commercial paper is secured only by ibm's reputation,
a. ibm does not have to pay back the principal.
b. the commercial paper can be issued only in $1,500 or $10,000 denominations.
c. no interest is paid.
d. no collateral is involved.
e. ibm has to pay interest rates higher than those charged by commercial banks for short-term loans.

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
