Assignment A scientist has developed a mathematical model for a physical process, and he wants to check how good is model is. To evaluate the correctness of his model, he wants to test the results of his model under certain parameters and compare them with experimental results. Write a program that first reads the number of tests (testCount) as an int followed by the results of each test according to the model as a double array. (testModel) and finally the results of each test according to experiments as a double array (testExperiment). Then, the program should calculate the error of the model by evaluating the average of the absolute values (i.e., mutlak değer) of the differences between the model result and experimental result (see formula below) using a function. testCount Error = testCount ItestModel; – textExperiment,1 i=1 NOTE: Individual absolute value of the difference between the model value and the experiment value calculations MUST be one in the function. Every other functionality MUST be done in the main function. NOTE: To calculate the absolute value of a number you MAY use the abs function. NOTE: testCount will always be a positive integer whose value will be at most 40. NOTE: The sizes of both testModel and testExperiment arrays will always be equal to testCount. 8 5 3 3.5 2.3 5.6 7.1 10.3 32.1 124.4-0.7 Input 92644 56 45 92 11 3 756 51 48 100 2.5 1.9 7.2 9.1 10.3 33.1 165.2 0.7 Output 1.4 5.3333 5.75

Both machinery and equipment groups have no scrap value and depreciated using straight-line method. New machinery & equipment is expected to increase sales by 3,250,000 annually, gross margin is 60% of sales, fixed operating costs stay the same. ACP stays at its original 45 days level, all sales on credit, credit purchases 10% of sales, payment period 60 days, inventory turnover is 6.5 times. Assume 1 year is 360 days.
