Use the value of the linear correlation coefficient r to find the coefficient of determination and the percentage of the total v
sergiy2304 [10]

Answer:

Step-by-step explanation:

Given that r = 0.952

We have coefficient of determination

r^2 =0.952^2\\=0.906304

=90.63%

This implies that nearly 91% of variation in change in dependent variable is due to the change in x.

The coefficient of determination is the square of the correlation (r) between predicted y scores and actual y scores; thus, it ranges from 0 to 1.

An R2 of 0 means that the dependent variable cannot be predicted from the independent variable.

An R2 of 1 means the dependent variable can be predicted without error from the independent variable.

How do you get why by itself in this equation? 4x+5y=5
Alja [10]

Answer:

first we get y on one side by itself.

4x+5y=5

we'll move x to the other side.

4x-4x+5y=5-4x

simplify.

5y=5-4x

now we get rid of the coefficient on y.

5y/5=(5-4x)/5

simplify.

y=5/5-4x/5

y=1- \frac{4}{5}x

The answer is y=1-\frac{4}{5}x
