Final answer:
The Texans have a better record, with a winning percentage of approximately 85.7%, compared to the Cowboys' 80%.
Step-by-step explanation:
To determine which team has a better record, we need to compare the winning percentages of the Cowboys and the Texans. The Cowboys have a record of 16 wins to 4 losses, which means their winning percentage is calculated as follows:
Winning Percentage of Cowboys = (Number of Wins / Total Games) = 16 / (16 + 4) = 16 / 20 = 0.80 or 80%
The Texans have a record of 18 wins to 3 losses. Their winning percentage is:
Winning Percentage of Texans = (Number of Wins / Total Games) = 18 / (18 + 3) = 18 / 21 ≈ 0.857 or 85.7%
Since the Texans have a higher winning percentage than the Cowboys, the Texans have the better record.
