The Previous question map coordinates and the shipping loads for a set of cities that we wish to connect through a central hub. City A B D E F G Map Coordinates (x,y) (6,10) (6,9) (3,8) (7,4) (6,9) (3,1) (1,6) Shipping Load 6 10 15 6 14 9 4 a) For the location of the proposed new central hub, the coordinates should be near XE (round your response to two decimal places). y=(round your response to two decimal places). b) If the shipments from city A triple, for the location of the proposed new central hub, the coordinates should be near: x=(round your response to two decimal places). y = (round your response to two decimal places)
