Q
Q: A student measures the length of a rod multiple times and records values of 10.1 cm, 10.2 cm, and 10.0 cm. What is the average length of the rod?
Solution:
Average length = (10.1 + 10.2 + 10.0) / 3 = 10.1 cm.
Steps: 6
Show Steps
Step 1: Write down all the measured values of the rod's length: 10.1 cm, 10.2 cm, and 10.0 cm.
Step 2: Add all the measured values together: 10.1 + 10.2 + 10.0.
Step 3: Calculate the total: 10.1 + 10.2 = 20.3, then 20.3 + 10.0 = 30.3.
Step 4: Count how many measurements you have. In this case, there are 3 measurements.
Step 5: Divide the total length by the number of measurements: 30.3 / 3.
Step 6: Calculate the average: 30.3 divided by 3 equals 10.1 cm.
