The formula for centripetal acceleration, a, is given in this formula, where v is the velocity of the object and r is the object's distance from the center of the circular path a = v^2

r

Solve the formula for r ​

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?
