Answer:
x is greater than or equal to 42 inches (I can't do the smybol for it)
Step-by-step explanation:
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.
