Charlotte is writing statements to prove that the sum of the measures of interior angles of triangle pqr is equal to 180°. line m is parallel to line n.

line n is parallel to line m. triangle pqr has vertex p on line n and vertices q and r on line m. angle qpr is 70 degrees. segment pq makes 35-degree angle with line n and segment pr makes 75-degree angle with line n.

which is a true statement she could write?

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?
