Suppose that a model is used with cost(y) as the dependent variable and with depth(x<1>) and downtime(x<3>) as input variables.This worksheet will use Mathcad and the matrix methods introduced later in the chapter by inserting a value of 1 for x<0>.X111111111111111150005200600065387109755680058207821086009026919799261081313800143113192412683455495524175686187676755046396419531165160121481206083914718014051137158560.6240000128746031.0099999904632500.6340000033378600.9029999971389770.5659999847412101.0340000391006401.2050000429153400.9060000181198121.0410000085830601.0399999618530202.5350000858306801.2050000429153402.7630000114440900.6610000133514401.1950000524520800.771000027656555:=...
