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.

City	Map Coordinates (x,y)	Shipping Load
A	(6,12)	6
B	(7,8)	11
C	(5,9)	15
D	(7,5)	5
E	(8,8)	15
F	(3,3)	10
G	(3,7)	6

a) For the location of the proposed new central hub, the coordinates should be near:

Part 2

x =

(round your response to two decimal places).

Part 3

y =

(round your response to two decimal places).

Part 4

b) If the shipments from city A

double,

for the location of the proposed new central hub, the coordinates should be near:

Part 5

x =

(round your response to two decimal places).

Part 6

y =

(round your response to two decimal places).
