The answer is the 2nd choice, number of sales.
The function described f(x) = B + Cx
10 times larger than a thousand. Also one decimal place larger
Answer:
Total no. of balls = 8
Red balls = 3
Yellow balls = 2
Green balls = 3
Now,
P (picking a yellow ball) = 2/8 = 1/4
P (picking a green ball) = 3/8

Take a look at the function

. You can simplify it to

. If x=0, then y=2 and when y=0, x=3. You obtain two points (0,2) and (3,0) that lie on the line

.
Since

, the line

should belong to the shaded area.
Now take point (0,0). Since

, you can conclude that point (0,0) belongs to the shaded area.Using all these thoughts, you can make a conclusion that the correct choice is B.
