Answer: The percent error in the player's guess is 9.5%.
Step-by-step explanation:
Given : A basketball player guesses her team will score 57 points during the game.
The player's team actually scores 63 points.
i.e. The actual core = 63 points
The estimated score = 57 points
Then , the percent error in the player's guess would be :
[tex]=\dfrac{|\text{Estimated score-Actual score}|}{\text{Actual score}}\times100\\\\=\dfrac{|57-63|}{63}\times100\\\\=\dfrac{|-6|}{63}\times100\\\\=\dfrac{6}{63}\times100=9.52380952381\%\\\\\approx9.5\%[/tex]
Hence, the percent error in the player's guess is 9.5%.
