The following table gives the map coordinates and the shipping loads for a set of cities that we wish to connect through a central hub. Shipping Load Map Coordinates (x,y) (5,11) (7,8) (5,9) (8,6) (8,9) (3,1) (1,7) a) 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). 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)
