Answer :
Answer: 30%
Step-by-step explanation:
Percent error = [tex]\dfrac{|\text{Estimated value - Actual value}|}{\text{Actual value}}\times100\%[/tex]
Estimated number of games win this year = 7
Actual number of games won = 10
Now , the percent error of Doug’s estimate = [tex]\dfrac{|7-10|}{10}\times100\%= \dfrac{3}{1}\times10\%=30\%[/tex]
Hence, the percent error of Doug’s estimate = 30%
