Which equation results from isolating a radical term and squaring both sides of the equation for the equation √(c-2)-√c=5?
C-2 = 25+
c-2= 25-c
C-2 = 25+c-1076
C-2 25+C+10

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?
