A company is considering two machines. Machine X has a first cost of $30,000, AOC of $18,000, and S of $7000 after 4 years. Machine Y will cost $50,000 with an AOC of $16,000 and S of $9000 after 6 years. The AW equations for Machine X and Y are: Select one: O a. AWX=-30,000(A/P,12%,12) –18,000 +7,000(A/F,12%,12); AWY= -50,000(A/P,12%,12) -16,000 + 9,000(A/F,12%,12) O b. AWX=-30,000(A/P,12%,6) –18,000 +7,000(A/F,12%,6); AWY= -50,000(A/P,12%,6) – 16,000 + 9,000(A/F,12%,6) O c. AWX=-30,000(A/P,12%,24) –18,000 +7,000(A/F,12%,24); AWY= -50,000(A/P,12%,24) -16,000 + 9,000(A/F,12%,24) O d. AWX=-30,000(A/P,12%,4) –18,000 +7,000(A/F,12%,4); AWY= -50,000(A/P,12%,6) - 16,000 + 9,000(A/F,12%,6)

A loan processing operation at a local bank processes an average of 7 loans per day. The operation has a design capacity of 10 loans per day and an effective capacity of 8 loans per day. What is the utilization of the processing operation? Select one: a. 100.0% b. 87.5% c. 70.0% d. 80.0% Warranty expense, the cost that a business incurs for the repair or replacement of goods that has sold, is an example of which of the following? Select one: a. Internal failure cost b. Appraisal cost c. Prevention cost d. External failure cost

There is a 4 percent error rate at a specific point in a production process. If an inspector is placed at this point, all the defects can be detected and eliminated. The inspector would cost $9 per hour and could inspect units in the process at the current production rate of 46 per hour. If no inspector is hired and defects are allowed to pass this point, there is a cost of $10 per defective unit to correct the defects later on.   Assume that the line will operate at the same rate (i.e., the current production rate) regardless of whether the inspector is hired or not. a. if the inspector is hired, what will be the inspection cost per unit? b. if an inspector is not hired, what will be the defective cost per unit? c. should an inspector be hired based on costs alone?

A rigid tank whose volume is 10 L contains 1 kg of water at 0.1 MPa pressure. The tank is now heated until the pressure is 20 MPa. Determine the amount of heat transfer for this process. Neglect kinetic and potential energy changes.

A large tank contains 50 gallons of water in which 10 lbs of salt is dissolved. Water containing 2 lbs of salt per gallon flows into the tank at the rate of 5gal/min .The mixture is kept well-stirred and flows out of the tank at the rate of 3gal/min Find: a) The amount of salt in the tank after 60 minutes. b) The amount of water in the tank after 60 minutes.

#5 Which of the following is a simulation? some method of generating virtual measurements that look like what would be gotten from a sample taking a series of measurements based on multiple samples measuring the mean and standard deviation of measurements from a sample specifying the expected mean and standard variation of measurements for an entire population
