# 4x100 Meter Relay

### Track, Baton, and a whole lot of Acceleration

## Speed, Strength, and Teamwork

The 4x100 meter relay is one of the most physically challenging events in all of the olympics. With sprinters reaching speeds of 27.78 mph it takes one special person to compete in this relay. The runners are in a team of four where each runner completes 100 meters each, in all running 400 meters.

## The Goal of the Study

The data below uses linear regressions and mathematical predictions to recognize trends in the performance of men and women in the 4x100 meter relay over 40 years. Using this data it is possible to determine which gender is currently out performing the other and if that trend will change in the future or has changed from what it previously was in the past.

## Data The data started in 1976. List 2 are the male gold medalist finish times (in seconds) and List 3 are the female gold medalist finish times. | ## More Data The data table continued | ## More Data The data table continued |

## The Intersection Point

## The Y Coordinate

The dependent or "y" value represents the seconds that it takes the sprinter to complete their portion of the 400 meters. The y-intercept is approximately 45.68 seconds. This would have approximately been the time of the gold medalist in the year 1753. Since the olympics would've happened a year before the time would have been slightly greater. The women's gold medalist time would've been the better/lesser of the two until the year 1753 when they would've been the same. Since 1753, men have and will always be the faster sex.
