Final answer:
The subject of this question is Mathematics. Emerson's strikeout rate is 32%.
Step-by-step explanation:
The subject of this question is Mathematics as we are dealing with numerical data. We are given that Emerson struck out 112 times in 350 at-bats.
To find the strikeout rate, we divide the number of strikeouts by the number of at-bats and multiply by 100 to get a percentage. So, the strikeout rate would be (112/350) * 100 = 32%.
Therefore, Emerson's strikeout rate is 32%.
