Pls help ASAP this is hard

1. 20, if you look at 2000 and where 20 at, the dot is there

2. i would say around 83 since it's not exactly at 80 and if it was in the middle it would be 85

3. around 26 because again it's not close to 30 and i count the difference between the dot in 2000 and 2001

4. in 2003 it was up by 150 since the dot is in the middle then in 2004 it got down by 125

5. 130 students will have colored hair in 2005.
