Answer:
1 / 16
Step-by-step explanation:
Number of options = 4
Number of correct answers = 1
Number points gained for a correct answer = 1
Number of points lost for an incorrect answer = 1/4 = 0.25
Probability of choosing a correct option = 1/4
Probability of choosing an incorrect option = 3/4
x ____ 1 ______ - 1/4
P(x) __ 1/4 ______ 3/4
Expected gain or loss :
E(x) = Σx*p(x)
E(x) = (1 * 1/4) + (-1/4 * 3/4)
E(x) = 1/4 - 3/16
E(x) = (4 - 3) / 16
E(x) = 1 /16
A gain of 1/16
No
It is not proportional, because when x = 0, y does not equal 0.
when x = 0, y = -4. Therefore, it doesnt pass through the origin.
Answer:
They exceed their goal by $150.
Step-by-step explanation:
If x = weekday shows and y = weekend shows, then
50(15) + 150(6)
750 + 900 = 1650
1650 - 1500 = 150
