The box has 2 blue balls, 5 red balls and n yellow balls. Now, you draw a ball from the box. You get 2000 dollors if you draw blue ball, 1000 dollors if you draw red ball, and 0 dollors if you draw yellow ball. If the expect value of draw a ball is 600 dollors, what is the value of n? (A)8 (B)9 (C)10 (D)11 (E)12​

answer: no

step-by-step explanation:

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
