<span>The word problem gives a rate of oil consumption at a rate of 25 gallons per 3 hours and 45 minutes. 3 hours and 45 minutes can be displayed as 3.75 hours. so you can say the generator consumes oil at a rate of 25 gallons per 3.75 hours. The following equation give you the oil consumption on a per hour basis; 25/3.75 and that gives you 6.67 gallons per hour. In 6 hours the generator will consume 40 gallons.</span>
Hope that it will help you
The probability that a student graduates given that the student plays one or more sports = probability that students play one or more sports and who graduate/probability that students play one or more sports
= 0.67 / 0.72
= 0.9306 (Answer)
The graph intersect the y axis in (0,1)
⇒ if x=0 ⇒ y=1
y+2= - 3/2(x-2)
if x=0 ⇒ y+2= - 3/2*(-2)=3 ⇒ y=1
when y=0 ⇒x<1
2= - 3/2(x-2)
2= -3/2x+3
2-3=-3/2x
x=-1:(-3/2)=2/3 <1
⇒ The answer is y+2= - 3/2(x-2)
