Final answer:
After calculating the win percentage, which is (12 games won ÷ 20 total games played) × 100%, the result is indeed 60%, so the statement is true.
Step-by-step explanation:
To determine if the statement "A soccer team that has won twelve games and lost eight games has a win percentage of sixty percent" is true or false, we start by calculating the win percentage using the formula:
Win percentage = (Number of games won ÷ Total number of games) × 100%
Here, the team has won 12 games, and the total number of games played is 12 games won + 8 games lost = 20 games.
Win percentage = (12 ÷ 20) × 100% = 60%
Thus, the statement is true.
