Use the quadractic formula
10 yellow cards over 30 = 10/30
second selection : 9 yellow cards over 29 = 9/29
10/30 * 9/29 = 1/3 * 9 /29 = 3/29 = 0.1034 = 10.34%

Answer:
C. graph Y
Step-by-step explanation:
Starting with f(r) = -3r +3, the inverse function can be found from ...
r = f(y)
r = -3y +3
r -3 = -3y
(r -3)/-3 = y
y = -1/3r +1
The inverse function will have a slightly negative slope and a y-intercept of 1. This matches graph Y.
