Exponential Decay of African Elephants
Transcript of Exponential Decay of African Elephants
y=the population of African Elephants
x= the number of years after 1900 a=12106888.11
Final Equation: y=12106888.11(0.9701839449)^x The correlation coefficient for this equation is 0.9429554475. This means that this equation fits the data very well, because correlation coefficient measures how close the points are to the line created by the equation. A perfect correlation would have a correlation coefficient of 1, so the closer the value is to one, the better the data correlates to the equation. In this case, 0.9429554475 is very close to one, so the equation fits the data very well. Next, the percent of the data points that are actually on the line created by the equation is 0.8891649759, or 88.91649759%. This means that the majority of the data fits exactly on the line created by the equation. In conclusion, this equation we are using to model the decrease in the elephant population fits well with the data we found. Graph: African Elephants Exponential Decay Predictions Usually, in an exponential decay graph, there is an asymptote, or a number that the line will get closer and closer too, by never actually touch. In the graph modeled by our equation, the asymptote would be y=0. Realistically though, there is no asymptote for this data, because if the elephant population continues to decline at this rate, they will become extinct. Based on our equation, if we don't do anything to help the African Elephants, there will be just over 1,000 of them left by the year 2200, and they will become completely extinct by the year 2439. For course that seems like a long way into the future, but there's no reason why we shouldn't start helping now! Thanks For Watching!! Bibliography
