Answer:
51% of the variation in Y is not explained by the regression line.
Step-by-step explanation:
To find the amount of variation not explained by the regression equation (how you found the correlation coefficient), we need to find <em>R. </em>We already have r ...
So to find R from r ( the correlation coefficient ) we just square it.
r² = .7² = .49
Then we just subtract that number from 1 to get the amount of <em>variation that is </em>not explained - which is ... .49 - 1 = .51 (convert to percent) = 51%
Answer:
y = x^2 + 3/4
Step-by-step explanation:

Answer:
Step-by-step explanation:
Find the y-intercepts, this should be sufficient to match with the graphs.
A.
- x = 0 ⇒ y = 1
- x = 0 ⇒ y = - 1
This is the graph 2
<h3 />
B.
- x = 0 ⇒ y = - 2
- x = 0 ⇒ y = 2
This is the graph 3
<h3 />
C.
- x = 0 ⇒ y = - 2
- x = 0 ⇒ y = - 2
This is the graph 1
