Question

Find the mean of 143,148,135,150,128,139,149,146,151,132

Answer 1

Answer:

143+ 148+135+150+128+139+149+146+151+132= 1421

1421/10 = 142.1

Answer 2

Answer:

The mean of the given data will be$\begin{aligned}\frac{1421}{10}\end{aligned}$.

Step-by-step explanation:

Given: $143,148,135,150,128,139,149,146,151,132$

We have to find the mean of the above data.

• As we know that the mean of a data set is the sum of the terms divided by the total number of terms.
• The formula is used to calculate the mean is:

         $\text { Mean }=\frac{\text { Sum of terms }}{\text { Number of terms }}$

We are solving in the following way:

We have,

$143,148,135,150,128,139,149,146,151,132$

Here,

$\text { Sum of terms }=143+148+135+150+128+139+149+146+151+132=1421\\\text { Number of terms }=10$

So, the mean of the above data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean } &=\frac{1421}{10}\end{aligned}$
