Answer 1

30%

Explanation:

Answer 2

Answer: 30%

Explanation:

Percent error =
`\frac{|\text{Estimated value - Actual value}|}{\text{Actual value}}*100\%`

Estimated number of games win this year = 7

Actual number of games won = 10

Now , the percent error of Doug’s estimate =
`(|7-10|)/(10)*100\%= (3)/(1)*10\%=30\%`

Hence, the percent error of Doug’s estimate = 30%
