A multiple regression equation with 2 independent variables has the following properties: . For every unit increase in $1, y decreases by 5.7 on average, holding a2 constant. For every unit increase in 2, y increases by 13.4 on average, holding ] constant. . When , = 0 and T2 = 0, 9 = 79. Which of the following best represents the equation? Og = 79 - 5.7x] - 13.412 Og = 79 + 5.7x] + 13.4x2 Og = 79 - 5.7x] + 13.4x2 Oy = 5.7x] + 13.4r, - 79 Oy = 79 + 5.721 - 13.4x2In an LP transportation problem, where m5 = units shipped from i: to 3', what does the following constraint mean? 32A 1 .1223 S 950 O demand node 2 has a requirement of 950 units from supply nodes A and B 0 supply node 2 can ship no more than 950 units to demand nodes A and B 0 supply nodes A and B can produce up to 9512] units for demand node 2 O demand nodes A and B have requirements of 950 units from supply node 2 O demand node 2 has a requirement of no more than 950 units from supply nodes A and B A student wanted to forecast demand data using weighted moving average while ensuring that more emphasis is placed on more recent data. In order to use the weights 6, 5, and 4 to forecast demand for period 7, the weight 4 should be assigned to period 05 04 09 07 08Winter jacket sales data will comprise primarily of which of the following time series components? O trend and cyclical O seasonal and exponential O random and trend O moving and exponential O seasonal and random
