Answer:
32% of the times at-bat.
Step-by-step explanation:
Since in Game 1, Emerson struck out 30 times in 90 times at bat; in Game 2, he struck out 40 times in 120 times at bat; and in Game 3, Emerson struck out 42 times in 140 times at bat; To determine what percentage of times at bat did Emerson actually hit the ball, the following calculation must be performed:
[tex]\frac{(30+40+42)}{(90+120+140)}=x[/tex]
[tex]\frac{112}{350} =x[/tex]
[tex]0.32=x[/tex]
Therefore he actually hit the ball 32% of the time.
