Solve the system of equations. y= 2x y= x^2 - 15

Xy x xy if a and b are positive integers such that a*b=9 and b*a=72 what is the value of a/b

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
