part b
what percentage of times at bat did emerson actually hit the ball?
%

Explanation:

Step1: Calculate total at - bats and strike - outs

Total at - bats \(=90 + 120+140=350\). Total strike - outs \(=30 + 40+42 = 112\).

Step2: Set up proportion for percentage

The formula for percentage is \(\frac{\text{strike - outs}}{\text{total at - bats}}=\frac{x}{100}\). Substituting values, we get \(\frac{112}{350}=\frac{x}{100}\).

Step3: Solve for \(x\) (percentage of strike - outs)

Cross - multiply: \(112\times100 = 350x\). Then \(x=\frac{112\times100}{350}\). Simplify: \(x = 32\).

Step4: Calculate percentage of hits

Percentage of hits \(=100 - 32=68\).

Answer:

68
