GPT 3.5
To find the total population of ladybugs after the swarm arrives, you need to add the current population to the number of ladybugs in the swarm.
Current population: 8.3 × 10^6
Swarm population: 950,000
To add these two values, you need to convert the swarm population to scientific notation:
950,000 = 9.5 × 10^5
Now, you can add the current population to the swarm population:
8.3 × 10^6 + 9.5 × 10^5 = (8.3 + 0.95) × 10^6 = 9.25 × 10^6
So, the total population of ladybugs in the region after the swarm arrives will be 9.25 × 10^6.
The correct answer is C. 9.25 × 10^6.
Current population: 8.3 × 10^6

To add these two values, you need to convert the swarm population to scientific notation:
950,000 = 9.5 × 10^5
Now, you can add the current population to the swarm population:
8.3 × 10^6 + 9.5 × 10^5 = (8.3 + 0.95) × 10^6 = 9.25 × 10^6
So, the total population of ladybugs in the region after the swarm arrives will be 9.25 × 10^6.
The correct answer is C. 9.25 × 10^6.
