Answer:
Explanation:
The answer is D- The number of flies decreased, then leveled off.
Easy. All you need to do us to is to shorten the number so that it only contains 3 digits. Change 2.9979248 to 2.99. Don't forget to round the number to the last possible digit. In this case, 2.997 would round to 3.00
So the answer would be 3.00x10^8.
Why?
Well, every non-0 number to the left of the decimal point will count as a significant figure. And every number to the right of the decimal point, whether it's 0 or not, will also count as a significant figure.
The 3 to the left of the decimal point and the 2 0s to the right will add up to 3 significant figures.
The answer is 2. Good luck
