9lbs 6 oz because there are 16 oz in a pound, remember that when subtracting the two
There are four 1/4’s per hour
Multiply the miles by 4:
15 3/4 x 4 = 63 miles per hour
1) in first place you must Know F(X) for every value of x
F(0) = 250(0.5)^0 = 250
f(1) = 250(0,5)^1 = 250*0,5 = 125
f(2)= 250(0,5)^2= 250*0,25 = 62,5
the average is = 250+125+62,5/ 3 = 145,83
