A skier skis along a circular ski trail that has a radius of 1.25 km. The skier starts at the East side of the ski trail and travels in the CCW direction. Let θ represent the radian measure of the angle the skier has swept out. Write an expression (in terms of θ) to represent the skier's distance to the East of the center of the ski trail (in km).
   

Write an expression (in terms of θ) to represent the skier's distance to the North of the center of the ski trail (in km).

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?
