<h3>
Answer: A) Only plot A</h3>
The reasoning is because all of the points for plot A are fairly close to the same straight line. This straight line has a positive slope. We call this line the regression line.
In contrast, plot B seems to have the points randomly scattered about. We can't draw a good fitting straight line to get near all of the points. So plot B does not show positive linear correlation.
Side note: the correlation coefficient for plot A will have its r value close to 1. The r value for plot B will be close to 0.

Answer: 1/3
<u>Divide</u>
30/90÷30/30=1/3
Since we are simplifying fractions we divide the numerator and the denominator by a number the fraction can go into.
We could use 10 then divide by 3. You can also just divide by 30 and get the answer.
Let's try dividing by 10 then 3!
30/90÷10/10=3/9
3/9÷3/3=1/3
As you can see we still get 1/3 when we divide by 3. Even tho you have to divide twice you still get 1/3. That's all that matters.
the reason that these are inverses is because if you switch x with z
and g(f(x))=x, then (x-9)/(x+5) is (z-9)/(z+5)=x. which implies that:
(z+5) - 14/(z+5)=1-(14/(z-5))=x.
(1/(1 - x) * 14) + 5 = z = g(x) maybe i messed up?
