Final answer:
Tommy's batting average is determined by dividing his 13 hits by his 44 at-bats, which equals 0.295 when rounded to the nearest thousandth.
Step-by-step explanation:
Tommy's batting average is calculated by dividing the number of times he got a hit by the total number of at-bats. To find Tommy's batting average, we use the formula:
Batting Average = (Number of Hits) / (Number of At-Bats)
Tommy got a hit 13 times and had 44 at-bats. So, his batting average would be:
13 / 44 = 0.2954545...
Rounding to the nearest thousandth, Tommy's batting average is 0.295.
