Suppose "true-talent" average exit velocity (AEV) on batted balls for all players is normally distributed with mean 86 mph and a standard deviation of 2 mph. For any sample of individual batted balls hit by one player, the standard deviation of exit velocity around a particular player's true-talent AEV is 8 mph. At this point in the season, Marco Masher has a total of 10 batted balls with an average exit velocity of 94 mph. Given only this information, the best estimate for his true talent exit velocity is closest to which whole number?

20+ ! come and answer quick! triangle mno is reflected over the x-axis and then translated up 4 and right 3. how can the transformation be amended such that the translation can occur before the reflection and have the image remain in the same position? a translate the pre-image down 4 and right 3 and then reflect the figure over the x-axis. b translate the pre-image up 3 and right 4 and then reflect the figure over the x-axis. c translate the pre-image up 4 and left 3 and then reflect the figure over the y-axis. d translate the pre-image down 3 and right 4 and then reflect the figure over the x-axis.
