Larry plays quarterback for the Eagles. During the team's opening football game, the Eagles have the ball 48 yards away from the
goal line. On the first play, the Eagles gain 31 yards on a pass toward the goal line. On the next four plays, the Eagles lose 3, 5, 7, and 4 yards, respectively. What is the distance between the ball and the goal line after these five plays? A -36 B-2 c 2 d 36
If the Eagles start with 48 yards left then gain 31, you would subtract 31 from 48. So 48-31=17. So they had 17 yards to go. On the next four plays the lose yards, so add up all the yards lost in those four plays. 3+5+7+4 which equals 19. So they were 17 yards away but then they lost 19 yards so you would add 17 and 19, which gives you 36. So therefore the ball is 36 yards away from the goal line after those five plays.
Using the empirical rule, the probability that a randomly selected student's math score is between 300 and 700 (both 2 standard deviations below the mean) is 95%. Or in decimal form, .95.
