Thank you!
1. To convert the number 2.28 x 10^-8 into standard form, we need to move the decimal point to the right until there is only one non-zero digit to the left of the decimal point. Since the exponent is negative, we will be moving the decimal point to the left.
Starting with 2.28, we move the decimal point eight places to the left because the exponent is -8. Each move to the left means dividing the number by 10.
Therefore, 2.28 x 10^-8 can be written in standard form as 0.0000000228. Looking at the answer choices, this corresponds to option c.
So the correct answer is c. 0.0000000228.
2. The player's batting average is found by dividing the number of hits by the number of times at bat. In this case, the player has 37 hits in 192 times at bat.
To find the batting average as a decimal, we divide 37 by 192:
37 / 192 ≈ 0.192708333
Rounding to the nearest thousandth means we look at the digit in the thousandths place, which is the 3. Since it is less than 5, we round down. Therefore, the player's batting average rounded to the nearest thousandth is 0.192.
Looking at the answer choices, this corresponds to option a.
So the correct answer is a. 0.192.
