A set of chemistry exam scores are normally distributed with a mean of 70 points and a standard deviation of 4 points. Cam got a score of 65 points on the exam.
What proportion of exam scores are higher than Cam's score?
You may round your answer to four decimal places.

The product of two negative rational numbers is always zero sometimes zero never zero

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.
