Question

If a pitcher strikes out 5 batters in 4 innings, how many batters is it likely he will strike out in 9 innings? Round to the nearest whole number.

Answer 1

ANSWER: 11 batters

5 divided by 4 = 1.25 batters striked out per inning
1.25 batters per inning x 9 innings = 11.25 batters which rounds down to 11

Answer 2

Answer: $\frac{45}{4}$ Batters or 11 batters (approx)

Step-by-step explanation:

Let in one inning the batters = x

Thus, in 4 inning total batters = 4x

But according to the question,

In 4 inning the number of batters = 5

Therefore, 4x = 5

⇒ x = 5/4

Thus, in one inning the batters = 5/4

⇒ In 9 inning the number of batters = 9 × 5/4 = 45/4 = 11.25 batters ≈ 11 batters
