Find the midpoint of cd if c= (9,2) d= (-7,-9)

An equation is shown below: 3(4x − 2) = 1 which of the following correctly shows the first two steps to solve this equation?

(40 points) i need some . an answer definition is appreciated as well.

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?
