Answer:
B
Step-by-step explanation:
90+45+45=180
All triangles equal 180.
Its B because if one angle is 90° then the other angles will equal each other. It cant be 60° and 30° because they dont equal, so your final answer is B.
Hope this Helps!!! :)
Answer:
The median is 2
Step-by-step explanation:
7 0 1 3 1 4 9 0
Arrange the numbers in order from smallest to largest
0 0 1 1 3 4 7 9
The median is the middle number
0 0 1 1 3 4 7 9
It is between 1 and 3, so average 1 and 3
(1+3)/2 = 4/2 =2
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%
