Answer:
According to the line of fit, after 20 hours of practice, the predicted number of strikeouts is 400.
Explanation:
The equation given is:
y = 20x + 0
where y represents the number of strikeouts and x represents the number of hours of practice. To find the number of strikeouts after 20 hours of practice, we substitute x = 20 into the equation and solve for y:
y = 20(20) + 0
y = 400
Therefore, according to the line of fit, after 20 hours of practice, the predicted number of strikeouts is 400.
