In getting the average of all the measurement you give you need first to sum all the measurements and also make sure that you do it properly. Then divide the sum with the number of measurements. By calculating the answer is 10.288

Answer:

10.2 cm

Step-by-step explanation:

Data : 10.05 cm, 10.1 cm, 9.741 cm, 10.6 cm, 10.5 cm

We are supposed to find the average

[tex]Average = \frac{\text{Sum of all observations}}{\text{No. of observations}}[/tex]

[tex]Average = \frac{10.05+10.1+9.741+ 10.6+10.5}{5}[/tex]

[tex]Average = \frac{50.991}{5}[/tex]

[tex]Average =10.1982[/tex]

Rounding off gives [tex]Average =10.2[/tex]

Hence the average of the measurements with the correct number of significant figures is 10.2 cm
