If the correlation coefficient between two variables is .90, what percent of the variance is explained by this correlation
ZanzabumX [31]

Answer:  81% of the variance in dependent variable is explained by this correlation .

Step-by-step explanation:

If r= correlation coefficient , then we say r^2<em>  </em>of the<em> </em>variance in Y is explained by Variable X.

Given: r= 0.90

(0.90)^2= 0.81

So, 81% of the variance in dependent variable is explained by this correlation .

10 feet = 1 inch

50 feet = 5 inches

Do the same thing for the length.

If you don't under stand.

50/10 = 5

1/10 = x/50

10x = 50

x = 50/10

x = 5 inches

Then you do the same with the lenght.
