Write the inequality shown by the graph a. y>-1/3 x+2 b. y>-1/3 x+2 c. y>-3x+2 d. y >-3x+2

Me find the measure to side c and the process to solve the problem you appreciate it : )

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?

What is the simplified form of square root of 400 to the 100th power ?
