B. I would probably say b. It can't be a because we are not given all the information about all the teenagers. It says "NO teen" we are not given the minimum and maximum
It can't be c because the margin of error is plus/minus 112.
It's not d because we are not calculating anything for age so there can be no margin of error for age.
Answer:
Yes!
Step-by-step explanation:
Yes, because 2>1.
Answer:
We need to add the expression: 
Step-by-step explanation:
As the first step, add the first two polynomials listed in order to find what their sum is. Do such by combining like terms:
now, you need to find another polynomial (let's call it P(x)) such that added to the one we just found above, will render 
as a result.
Putting this phrase in mathematical terms, we write:
Now we solve for this unknown P(x) in this equation, by subtracting each of the terms that are accompanying it on the left side of the equation. We do one at a time for clarity:
Therefore, the expression we need to add is:

Calculate the spray interval to spray 5 times a day
----------------------------------------------------------------------
one day = 24 hour
24 ÷ 5 = 4.8 hours
----------------------------------------------------------------------
Find the interval in minutes
----------------------------------------------------------------------
4.8 hours = 4h 48 mins
4.8 hours = (4 x 60) + 48
4.8 hours =288 mins
----------------------------------------------------------------------
Answer: 288 mins
