Quizplus · Accepted Answer

- Add the two numbers in the numerator: 1.302 + 953.2 = 954.502
- Divide by 2.0: 954.502/2.0 = 477.251
- The least precise measurement in the problem has 3 significant figures (2.0), so the answer should also have 3 significant figures.
- Rounding 477.251 to 3 significant figures gives: 4.8 × 10¹². 
- Therefore, the best choice is C (4.8 × 10¹² with proper scientific notation and 3 significant figures).
