The population of the state of California was about 37,250,000 people in 2013. Which number best approximates the population as a single digit times a power of 10?
A. 3 × 10⁻⁶
B. 4 × 10⁻⁷
C. 3 × 10⁶
D. 4 × 10⁷
Answer:
Option D = 4 × 10⁷
Step-by-step explanation:
We are given the population of people = 37,250,000 people
We round to a power of 10
and that would give us 3.7 × 10⁷
We are told in the question to approximate the population as a single digit,
3.7 × 10⁷ s a single digit = rounding up to the nearest whole number
= 4 × 10⁷.
Therefore, the number that best approximates the population as a single digit times a power of 10 is
= 4 × 10⁷
