The first statement is false and answer to second statement is no.

The mentioned information does not state that x and y are linearly related or not. If they are not related in linear way, the mean value of y would not be located at the mean of the x values.

Confidence intervals indicate the mean or population of the sample. For the confidence interval of sales of pizza stores, the similar data would be required for comparison using statistics tool. Hence, the relevant data should be sales of nearby pizza stores till now. Thus, the mentioned statement is irrelevant.

Complete the square to rewrite the following equation. Identify the center and radius of the circle. You must show all work and
Bond [772]

<em>x</em> ² - 4<em>x</em> + <em>y</em> ² + 8<em>y</em> = -4

(<em>x</em> ² - 4<em>x</em> + 4) + (<em>y</em> ² + 8<em>y</em> + 16) = -4 + 4 + 16

(<em>x</em> - 2)² + (<em>y</em> + 4)² = 16

(<em>x</em> - 2)² + (<em>y</em> + 4)² = 4²

which is the equation of a circle centered at (2, -4) and with radius 4.
