5.05 + 5 + 5.1 = 15.15cm Then you just divide it by the amount of measurements you had like this:15.15 รท 3 = 5.04999971cm Then you can just round it to the 3rd figure: 5.05cm < And that's the mean/average length of the bar. :) (Or the one above if you want all of the decimals too)
To calculate the average length of a copper bar based on the measurements provided by three chemistry students, you add all the measurements together and then divide by the number of measurements. The measurements are 5.05 cm, 5 cm, and 5.1 cm.
First, find the sum of the measurements:
5.05 cm + 5 cm + 5.1 cm = 15.15 cm
Next, divide this sum by the number of measurements, which is 3:
15.15 cm รท 3 = 5.05 cm
Therefore, the average length of the copper bar is 5.05 cm.
To calculate the average length of the copper bar, first add the recorded lengths together to get a total of 15.15 cm. Then divide this total by 3, which gives an average length of 5.05 cm. Thus, the average measurement is confirmed to be 5.05 cm.
