18. After the GAme: All the Autographed Balls (Total Valued at over $1500)
19. Hidden Math in Baseball: Batting Average: # of hits divided by # of at bats. Ex: 200 hits in 650 at bats is a .307 BA Earned Run Average: # of earned runs divided by # of innings pitched multiplied by 9 On Base Percentage: # of times reaching base divided by total # of at bats Slugging Percentage: # of singles + (2 X # of doubles) + (3 X # of triples) + (4 X # of homeruns) all divided by the total # of at bats Predicting the probability of scoring runs = (Hits + walks) + (Total Bases) / (At Bats + Walks) Probability of winning a game: ½ X Runs scored season / Opponents’ Runs scored The baseball “diamond” is really a square with 90 foot sides The Pythagorean theorem can be used to find the distance from home plate to second base or from first base to third Ex: 90^2 + 90^2 = C^ 2 (8,100 +8,100) = 16,200 and the square root of that is 127.3 feet between
20. Hidden Math in Baseball (Cont. ) The third base and first base foul lines intersect at home plate, creating 90 degree angles The pitching mound, a circle, has an 18 foot diameter Around first, second, and third base, there are 13 foot arcs The angle at which a batter hits the ball is very important. For example, if a right handed batter connects his bat with the ball at a 90 degree angle, the ball will go to second base, on the right side of the infield. However, if the same batter hits the ball at a 45 degree angle, the ball will go to the left side of the infield, by the shortstop.
21. Concept from another class: Ap Environmental science There are multiple irrigation techniques that are used to manage crops and fields worldwide including flood irrigation, furrow irrigation, drip irrigation, and center pivot sprinkler systems After the 1995 season at Dodger Stadium, the 100,000 square feet of Bermuda grass is grown on sand, and below the sand is a vacuum layer that holds a water tight barrier to hold rain water in. Moisture is monitored and controlled by a computer so that the grass will grow perfectly. This is an example of drip irrigation because water is released through open tubing mounted below ground near the roots of individual plants.
