Unlike the other species, the humans were able to use their superior brain power in order to construct sophisticated tools. These tools were able to perform tasks that were not possible by only using what nature provided as strengths. This gave a huge advantage for the humans, as by using the tools they were able to transform the environment as it suited them, thus controlling it. This was not achieved individually though, but instead the humans have developed complex social structure, so they were cooperating for the common good. Working together in large groups, and having technology on their side, the humans propelled themselves on top, becoming the biggest force among the living organisms.
I can give you one method: you'll have to find what to call it.
1) take the attendance of the last five years; add all numbers and divide by 5 to give you the average attendance.
Just thought of this:
2) again look at last 5 years; see if you can get a percentage of increase for each year.
Did it increase 5% or more each year? Then take the % from just the previous year (2014) & give that to the 2015 race to project for 2016 race.
To boil the egg in exactly 15 minutes, follow these steps.
1. Start both hourglasses as you start boiling the egg.
2. After the 7-minute hourglass runs out, turn it to start it again.
3. Four minutes later, when the 11-minute hourglass runs out, turn the 7-minute hourglass again.
4. Wait for the 7-minute hourglass to run out, which will take another four minutes and get you to exactly 15 minutes of boiling time.
