Solve the problem by writing a variation model. the distance that a car can go varies directly as the number of gallons of gasoline it consumes. if a car can go 276 miles on 12 gallons of gasoline, how far can it go on a full tank of 19 gallons?

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
