The X intercept is (9,0) while the Y intercept is (0,21)
Sum of two sides can not be smaller than third side and difference of two sides cannot be larger then third side.
Answer is B.
Applying the percentages, and considering that 70% of the first group drinks at least 2 glasses of water a day, it is found that 0.725 = 72.5% of the team drinks at least 2 glasses of water a day.
The team is divided into two equal groups, hence, each represents 50%.
The <em>percentages </em>associated with drinking at least 2 glasses of water a day is:
- 70% of 50%(first group)
- 75% of 50%(second group)
Hence, applying the weighed percentage, the total percentage is:

0.725 = 72.5% of the team drinks at least 2 glasses of water a day.
