Given points P(1, -2) and Q(5,9) on directed line segment PQ, what is the y-coordinate of
point B that partitions segment PQ with the ratio
3: 7?

Use the elimination method to solve the systems of equations. choose the correct ordered pair. 7x+4y=39

Find the ratios of the corresponding sides

Afootball quarterback has two more chances to throw a touchdown before his team is forced to punt the ball. he misses the receiver on the first throw 25% of the time. when his first throw is incomplete, he misses the receiver on the second throw 15% of the time. what is the probability of not throwing the ball to a receiver on either throw?
