The height of a triangle is 1 less than 4 times the corresponding base. If the area of the triangle is 69 square meters, what is the base of the triangle? (Hint: area of triangle=12⋅base⋅height) Match each expression with the correct equation in standard form that models this situation, where b represents the base of the triangle, or solution.

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?
