Concept explainers
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).
