Reflecting on the Measurement of Leaf Lengths
What is the average length of the five leaves measured by the student?
The student measured the length of five leaves using a centimeter ruler. The lengths are as follows:
- Leaf 1: 6.17 cm
- Leaf 2: 6.05 cm
- Leaf 3: 5.95 cm
- Leaf 4: 6.05 cm
- Leaf 5: 6.10 cm
What is the average length of the leaves to the nearest hundredth?
Answer:
The mean length of the leaves can be calculated by summing up all the measurements and dividing by the total number of leaves measured.
To find the average length, we add up all the measurements: 6.17 cm + 6.05 cm + 5.95 cm + 6.05 cm + 6.10 cm = 30.32 cm. Then we divide the total by the number of measurements (5): 30.32 cm / 5 = 6.064 cm.
Rounded to the nearest hundredth, the mean length of the leaves measured by the student is 6.06 cm.
Therefore, the average length of the five leaves is 6.06 cm.
