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.

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
