Luba_88 [7]

Answer:

45 possible connections

Step-by-step explanation:

The general equation for finding the possible number of connections in a network is given as

$\frac{n*(n - 1)}{2}$

where n is the number of computers on the network.

for 4 computers, we'll have

$\frac{4*(4 - 1)}{2}$ = $\frac{4*3}{2}$ = 6

for 5 computers, we'll have

$\frac{5*(5 - 1)}{2}$ = $\frac{5*4}{2}$ = 10.

therefore, for 10 computers, we will have

$\frac{10*(10 - 1)}{2}$ = $\frac{10*9}{2}$ = 45 possible connections
