You must show all your work for this section. 4 solution is not considered to be correct umless t is accompanted by complete and correct supporting work 24) Solve the linear system using Gauss-Jordan elimination x-y +2z = 0 3x+ y + z = 13 25) Solve the equation 500-2) 625 26)Solve the equation log(4 + x)-log(-5)-log 2.Explanation / Answer
22)
If the first marble is white, there are only 7 marbles to select blue one.
Hence required probability = 1/7 (Option A)
23)
probability of getting 4 is 1/6
P(X = 2) = 5C2 * (1/6)^2 * (1/6)^4 = 0.000214335
Option D
