On a coordinate plane, 2 triangles are shown. The first triangle has points X (2, 5), Y (2, 3), Z (4, 3). The second triangle has points X prime (negative 2, negative 5), Y prime (negative 2, negative 3), Z prime (negative 4, negative 3). What are the vertices for the final image after applying the composition T−2,4 ◦ RO,180° to ΔXYZ?

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?
