Match the statements
1. m< 2 = 122° and m< 3 = 58°
if corresponding angles are equal, then lines are parallel.
2. 3 and 5 are supplementary angles
exterior sides in opposite rays
3. m< 3 + m< 5 = 180°
given
4. 58° + m< 5 = 180°
second substitution
5. m< 5 = 122°
definition of supplementary angles
6. m< 2 = m5
first substitution
7. l || m
subtraction property of equality

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?
