Eliosa determined that the correlation coefficient of the data set -0.7. what percent of the total variation in the y-values is not explained by the regression line?

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 R. 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 variation that is not explained - which is ... .49 - 1 = .51 (convert to percent) = 51%

unless if u could do my questions, if not i wouldn't want to

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
