Consider a network model in which edges are placed independently between each pair of vertices i, j with probability pij = kfifj , where k is a constant and fi is a number assigned to vertex i. show that the expected degree ci of vertex i in this model is proportional to fi and hence that the only possible choice of edge probability with this form is pij = cicj/2m, as in the chung-lu model.

1 is c

2 is a

3 is a

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
