1. Compute return on investment for each center. Using return on investment, which center is most efficient at using assets to generate income

Diversified semiconductors sells perishable electronic components. some must be shipped and stored in reusable protective containers. customers pay a deposit for each container received. the deposit is equal to the container’s cost. they receive a refund when the container is returned. during 2018, deposits collected on containers shipped were $856,000. deposits are forfeited if containers are not returned within 18 months. containers held by customers at january 1, 2018, represented deposits of $587,000. in 2018, $811,000 was refunded and deposits forfeited were $41,000. required: 1. prepare the appropriate journal entries for the deposits received and returned during 2018. 2. determine the liability for refundable deposits to be reported on the december 31, 2018, balance sheet.

Stocks a, b, and c are similar in some respects: each has an expected return of 10% and a standard deviation of 25%. stocks a and b have returns that are independent of one another; i.e., their correlation coefficient, r, equals zero. stocks a and c have returns that are negatively correlated with one another; i.e., r is less than 0. portfolio ab is a portfolio with half of its money invested in stock a and half in stock b. portfolio ac is a portfolio with half of its money invested in stock a and half invested in stock c. which of the following statements is correct? a. portfolio ab has a standard deviation that is greater than 25%.b. portfolio ac has an expected return that is less than 10%.c. portfolio ac has a standard deviation that is less than 25%.d. portfolio ab has a standard deviation that is equal to 25%.e. portfolio ac has an expected return that is greater than 25%.

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
