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:

For X = Independent variable and Y=dependent variable,

If r= correlation coefficient , then we say $r^2$ of the 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 .

sleet_krkn [62]

Step-by-step explanation:

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.
