Apair of jeans cost 89. a jean jacket costs twice as much. what is the total cost of a jean jacket and 4 pairs of jeans?

(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

When you answer this can you explain

Solve the equation -9p - 17 =10 a -3 b. 16 c. 18 d -16
