Circle c lies on the coordinate plane with its center at (2,−16).
point a(2,−13) lies on circle c.
which equation verifies that the point p(−1,−16) lies on circle c?
(2−1)2+(−16−16)2=(2+2)2+(−16−13)2 (2+16)2+(−1+16)2=(2+2)2+(−16−13)2 (2+1)2+(−16+16)2=(2−2)2+(−16+13)2 (2−16)2+(2−13)2=(2−16)2+(−1−16)2

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
