The answer is 95%
This is something you should memorize. Specifically it is from the Empirical Rule (or 68-95-99.7 rule) which gives rough approximations of areas under the curve.
Answer:
All real numbers except 3
Step-by-step explanation:
Given

Required
Determine the domain
We start by writing the following inequality

Add 6 to both sides


Divide both sides by 2



<em>As such, the domain of x is all real numbers except 3</em>
It's 448 square feet so you'll require 1 and some. buy 2 gallons
Answer:
The average is 124
Step-by-step explanation:
When x=2 substitute into the equation given above
-3^2+79
9+79=88...(1)
When x=4
-3^4+79
81+79=160(2)
Average of (1) and (2)
160+88/2
=248/2
=124
Therefore the average rate is 124
