Question

The length of a rod as measured in an experiment was found to be

2.48m, 2.46m, 2.49m, 2.50m, and 2.48m. Find (i) mean length (ii)

absolute error (iii) mean absolute error(iii) Relative error (iv) percentage

error .

​

Answer 1

Explanation:

There are several undefined terms which we should keep in mind. They are consistent, because they deal with two different situations:

(i) says that the given two points A and B, there is a point C lying on the line in between them;

(ii) says that given A and B, we ca take C not lying on the line through A and B.

These ‘postulates’ do not follow from Euclid’s postulates.

However, they follow from axiom stated as given two distinct points; there is a unique line that passes through them..
