Angela tried to solve an equation step by step. \begin{aligned} \dfrac34+m&=\dfrac54 \dfrac34+m-\dfrac34&=\dfrac54+\ dfrac34&\green{\text{Step } 1} m&=2&\blue{\text{Step } 2} \end{aligned} 4 3 ​ +m 4 3 ​ +m− 4 3 ​ m ​ = 4 5 ​ = 4 5 ​ + 4 3 ​ =2 ​ Step 1 Step 2 ​

Divide. reduce the answer to lowest terms.5 2/3 ÷ 3 1/9

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?
