Question

2 find the mean of the given set of numbers. 1,4,2,2,0,9

Explanation:

Step1: Calculate the sum of the numbers

The sum of the numbers \(1 + 4+2 + 2+0 + 9\) is \(1+4 = 5\), \(5+2=7\), \(7 + 2=9\), \(9+0 = 9\), \(9+9=18\). So, the sum \(S=18\).

Step2: Calculate the number of elements

The set of numbers \(1,4,2,2,0,9\) has \(n = 6\) elements.

Step3: Calculate the mean

The formula for the mean \(\bar{x}=\frac{S}{n}\). Substituting \(S = 18\) and \(n=6\), we get \(\bar{x}=\frac{18}{6}=3\).

Answer:

\(3\)
