we are given

To find solution , we can factor it and then we can solve for x
step-1: Factoring


step-2: Solve for x




so, option-C and option-F...........Answer
a) the answer of the substitute is 300
b) the answer of the substitute is 7027/300 or 23.423
Answer:0.001
x=the number of workers taking the bus to work
p= probability of success =(15/100) = 0.15
q= probability of failure =1- p = 0.85
P(X=6) = 10C6(0.15)^6(0.85)^4
= 0.001
