To find the total of the given measurements with the correct precision, follow these detailed steps:
1. List the Measurements:
- 2.11 mL
- 5.83 mL
- 7.64 mL
- 10.5 mL
- 8.33 mL
2. Sum the Measurements:
- Add all the measurements together: [tex]\(2.11 + 5.83 + 7.64 + 10.5 + 8.33 = 34.41 \text{ mL}\)[/tex].
3. Determine the Decimal Precision:
- Look at the decimal places in each measurement:
- 2.11 has 2 decimal places
- 5.83 has 2 decimal places
- 7.64 has 2 decimal places
- 10.5 has 1 decimal place
- 8.33 has 2 decimal places
- The measurement with the least number of decimal places is 10.5, which has 1 decimal place.
4. Apply the Correct Precision:
- When adding measurements, the result should be reported to the least number of decimal places of any measurement in the sum.
- Therefore, the total [tex]\(34.41 \text{ mL}\)[/tex] should be rounded to 1 decimal place.
5. Round the Total:
- Round 34.41 to one decimal place: [tex]\(34.41 \rightarrow 34.4 \text{ mL}\)[/tex].
Therefore, the sum of the measurements with the correct precision is [tex]\(34.4 \text{ mL}\)[/tex].
