For each quadratic equation, determine the solutions using the Zero Product Property or the Quadratic Formula. Then verify your answer using a table or a graph of the related function. For example, for Problem 1, use a graph or table of y = x2 + 2x β 15 to verify your algebraic solution. x2 + 2x β 15 = 0 2x2 + 7x + 3 = 0 x2 + 4x = 17 3x2 = 6 5. Write a quadratic equation in standard form that has solutions x = 2 and x = β2. 6. Write a quadratic equation in standard form that has solutions x = 2 Β± 3.

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?
