For this case we have to:
x: Variable that represents the number of times Henry visits the art museum.
If you pay 15 for parking and 25 for admission every time you go, we have:
Now, if you buy a membership at a net cost (it does not depend on the number of visits to the museum) of $ 110 and only pay $ 10 of parking, every time you attend the museum, we have:
Finally, the two equations that represent the situation are:
Answer:
Option A
Answer 1:
Answer 2:
Note: BOTH of those answers are correct. Chose either one.
<u>Factor left side of equation</u>
<u></u><u></u>

<u>Set factors equal to 0</u>

Answer:
<u>Explanatory variable</u> (independent variable)
<u>Response variable</u> (dependent variable)
(a) As the class wondered if they could <em>predict the father's height</em>, when they<em> know the son's height</em>
Explanatory variable = son's height
Response variable = father's height
(even though this is contrary to real-life, where the father's height would be used to predict the son's height)
(b) **see first attachment**
(c) The association is positive since the father's height increases as the son's height increases.
(d) **see second attachment**
Outlier = Paul (64.5, 73)
This point is far away from the majority of points on the scatter plot.
If we add a regression line to the scatter plot, we can see that this data point is the farthest from the regression line.
