Problem Statement: Project Selection (and Binary Decision Variables) Suppose that you are modeling a project selection problem as a Linear Program with binary decision variables. There are five projects to choose from: Projects 1 through 5 . We define the following binary decision variables: xi=1, if Project i is selected, and xi=0 if Project i is not selected for i=1,2,3,4,5. Please use these binary decision variables to write linear constraints that implement the restrictions specified in the following questions. Answer these questions independent of each other. In other words, if Project 5 is selected, then at least one of Projects 2,3 or 4 must also be selected. Please type your answer in the space below using decision variables "x2", "x3", "x4" and " x5 " and relation signs "=", "=
