A manager is trying to estimate the appropriate learning curve for a certain job. The manager notes that the first four units had a total time of 30 minutes. Which learning curve would yield approximately this result if the first unit took 10 minutes?

using the attached cumulative improvement factor table, the cumulative factors for 4 units are:

60% = 2.405

65% = 2.578

70% = 2.758

75% = 2.946

80% = 3.142

85% = 3.345

90% = 3.556

95% = 3.774

what factor multiplied by 10 = 30

factor = 30/ 10 = 3

using the attached table, the closest factor is 2.946 for 75%

using a learning curve calculator, the closest factor we can get is 2.9849 for 76%.

Secured loans are protected by collateral security. examples: title loans where the borrower uses the car title as collateral security interest rates are lower and repayments are longer therefore risk is low as a collateral security is given as guarantee to the bank in case of failure to pay the loanunsecured loans are not protected by collateral security but it is given on the creditworthiness of the borrower, trusting that she/he will pay on time. examples; payday loans is a short term loan where the borrower lends money from the bank and pays is back when the borrower receives his/her wages.interest rates are high and repayments are shorter. but the risk is high as no collateral security is given as a guarantee to the bank for payment of the loan
