B is the midpoint of AC, AB=5x and BC=2x+9 find AB, BC, and AC

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

(a) (8%) compute the probability of an even integer among the 100 integers 1! , 2! , 3! , until 100! (here n! is n factorial or n*(n-1)*(n-2) *… 1) (b) (16%) compute the probability of an even integer among the 100 integers: 1, 1+2, 1+2+3, 1+2+3+4, …., 1+2+3+… + 99, and 1+2+3+… + 100
