A regression equation is obtained for a collection of paired data. It is found that the total variation is 20.711, the explained

Deffense [45]

Answer: $R^{2}$ = 0.89

Step-by-step explanation:

Coefficient of determination is represented by $R^{2}$ . This tells us that how much of the variation in the dependent variable is explained by the independent variable.

It is the ratio of explained variation by the independent variables to the total variation in the dependent variable.

Hence,

Coefficient of determination = $\frac{Explained\ Variation}{Total\ Variation}$

= $\frac{18.592}{20.711}$

$R^{2}$ = 0.89

∴ 89% of the variation in the dependent variable is explained by the independent variables.

Which equation represents a circle whose center is located at (- 6, 2) and whose radius is sqrt(10) units?

Answer:

${(x + 6)}^{2} + {(y - 2)}^{2}=10$

Step-by-step explanation:

The equation of a circle with center (a,b) and radius r, is

${(x - a)}^{2} + {(y - b)}^{2} = {r}^{2}$

From the question, the center of the circle is located at (-6,2) and the radius is

$r = \sqrt{10}$

We substitute the center and radius to get:

${(x - - 6)}^{2} + {(y - 2)}^{2} = {( \sqrt{10} })^{2}$

Simplify to obtain:

${(x + 6)}^{2} + {(y - 2)}^{2}=10$
