Answer:
-3 ≥ x ≥ 9
Step-by-step explanation:
The domain are the x-values of every point in your graph. Since it a continuous domain, it'll be represented with ≥. Your two extremities are -3 and 9. Therefore, your domain is -3 ≥ x ≥ 9.
Answer: The answer is it would take Dan and Stan 1 hour if they work together, because 3-2=1, so make those hours and you have 1 hour.

Answer: choice A
---------------------------------------------------------------------
---------------------------------------------------------------------
Work Shown:
P(TV) = (number who watch tv)/(number total)
P(TV) = 30/100
P(TV) = 0.30
P(Girl) = (number of girls)/(number total)
P(Girl) = 55/100
P(Girl) = 0.55
P(TV)*P(Girl) = 0.30*0.55 = 0.165 which rounds to 0.17
We'll use this value later. So let's call this M = 0.17
Look in the "girl" row and "tv" column. The value 17 is here.
This is out of 100 people total, so
P(TV and Girl) = 17/100 = 0.17
Call this value N = 0.17
Because M = N = 0.17 approximately, this means that the two variables "TV" and "Girl" are approximately independent
So the equation P(TV and Girl) = P(TV)*P(Girl) is approximately true in this example.
This points to choice A being the answer.
