Which rule represents the reduction of a figure?
(x, y) (7/2x, 7/2,y)
(x, y) (2.3x, 2.3y)
(x, y) (x+ 1/3, y+1/3)
(x, y) (0.52x, 0.52y)

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=

An office supply company conducted a survey before marketing a new paper shredder designed for home use. in the survey, 80 % of the people who tried the shredder were satisfied with it. because of this high satisfaction rate, the company decided to market the new shredder. assume that 80 % of all people are satisfied with this shredder. during a certain month, 100 customers bought this shredder. find the probability that of these 100 customers, the number who are satisfied is 69 or fewer.
