The answer is the graph has a relative maximum
You have to split it into triangles
but you have to know how to use pythagorus in 3D shapes
(x-9)(x+7)=0
x-9=0 or x+7=0
x=9 or x=-7

Answer:
A
Step-by-step explanation:
We know that in normal distribution, approximately 34% of bags will fall with in one standard deviation on one side. On both sides within the range of 1 standard deviation, 34 + 34 = 68 % of bags will fall.
Our range is:
1600 to 1620
1610 - 10 to 1610 + 10
So the answer is 1
That means, that 68% is the answer.
