Answer 1

Answer:

If the readings of thickness of metal plate are 1.612 cm, 1.611 cm, 1.613 cm, 1.612 cm respectively, then the average reading will be 1.612cm

Answer 2

Answer:

For the given 4 readings the average will be the sum of all the 4 readings, and dividing it by 4: 1.612cm

Explanation:

As per the given statement,

We are required to get the average of the given readings.

To do this, firstly, take the sum of all the given figure values, and then, divide the number of observations.

In this case, it's 4.

And the sum is, 1.612 cm +1.611 cm + 1.613 cm + 1.612 cm = 4.448 cm.

Finally, when we divide the sum by, 4 it's 1.612.

Since the values are in 3 decimals, it  indicates that the reading are taken very precisely., and so the average in this case are very important.

So, the average reading will be: 1.612 cm
