Question 2 (1+2+1+7+2 marks] We are trying to rank the web pages in the following network according to the PageRank algorithm. You may find the Information Sheet useful for this question. (a) Find the number of links leaving each page, . (b) Write an equation for the weight of each page, by adding the number of links from each page divided by the total number of links leaving that page. EIBT, 2019 (c) Write a matrix equation of the form AX = X and rearrange this to the form (4-1)X = 0. In other words, write a matrix equation with the right hand side equal to the zero vector. (d) Perform row operations on the matrix 4-1 until you are able to solve it using an unknown parameter t. Note that you need not go all the way to reduced row echelon form, or even row echelon form to solve this system, but it will not hurt to do so. (e) By putting 1 = 1 in your solution to (d), find the weight of each page and rank them from highest rank to lowest
