A supplier of kerosene has a 150-gallon tank that is filled at the beginning of each week. His weekly demand shows a relative frequency behavior that increases steadily up to 100 gallons and then levels off between 100 and 150 gallons. If Y denotes weekly demand in hundreds of gallons, the relative frequency of demand can be modeled by a Find F(y). b Find P(0 ≤ y ≤.5). C Find P(.5 ≤Y ≤ 1.2). f(y) = y, 1, 0, 0≤ y ≤ 1, 1< y ≤ 1.5, elsewhere.
