When Ryan is 10, his brother Kyle is 14. When Ryan is 16, Kyle will be 20. When Ryan is 21, Kyle will be 25. Let r represent Ryan's age, and let k represent Kyle's age." Fill in the table, then enter and solve an equation expressing k in terms of r to find Kyle's age when Ryan is 50.

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?
