If the correlation coefficient between two variables is .90, what percent of the variance is explained by this correlation
1 answer:
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 <em> </em>of the<em> </em>variance in Y is explained by Variable X.
Given: r= 0.90
So, 81% of the variance in dependent variable is explained by this correlation .

Division is one of the basic mathematical operations. The cost of Brand A and B is the same.
<h3>What is division?</h3>The division is one of the most basic arithmetic operations. It is used to find the number of times a number is been added to itself.
Given to us
Brand A: 14 ounces for $44.66
Brand B: 20 ounces for $63.80
To compare the two brands we will find the cost of one ounce for each brand.
For Brand A,
The cost of 14 ounces is $44.66, therefore,
For Brand B,
The cost of 20 ounces is $63.80, therefore,
From the above two values, we can conclude that the cost of Brand A and B is the same.
