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 f(y) = { y, 0 ≤ y ≤ 1
1, 1 < y ≤1.5
0, elsewhere.
Find
P(0 ≤ Y ≤ .5)

step-by-step explanation:

it's the only multiple of both and the least

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
