Aproduction line has three machines a, b, and c, with reliabilities of .99, .96, and .93,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 (i. e., a series backup), and plan 2 involves providing a backup for each machine (i. e., a parallel backup). in either case, three additional machines (a, b, and c) would be used with reliabilities equal to the original three.

a. which plan will provide higher reliability?
b. explain why the two reliabilities are not the same.

the answers are in the images, i received 100% on this assignment. hope this !

i think the answer is true

step-by-step explanation:

answer:

some responsibilities that come with having a checking account -

1. we have to maintain check register with exactness to avoid checks being returned for insufficient funds which is called bouncing a check.

2. we need to update our check register each time we make a transaction using a convenience card. updating check register will   save   us from   overdrawing of checking account.

3. read the agreement the bank gave you when you signed up for our checking account. this includes all the fees and the minimum balance we need to keep in our account to avoid maintenance charges.  

explanation:

note : -   checking account is a transactional deposit account. we can use it to deposit and withdraw funds. money in a checking account is very liquid. it   can be withdrawn using electronic debits, automated cash machines, or checks among other methods.
