Answer 2

Answer:

The mean of the given numbers is 1.15.

Step-by-step explanation:

Mean:

• The mean of the data also known as the average is given by the ratio of the sum of all the values of the data to the total number of the elements in the data.
• The mean of the data set can be written as

        $\overline x=\dfrac{x_1+x_2+x_3+...+x_n}{n}=\dfrac{\Sigma x}{n}$

        where n is the number of the elements.

Given the numbers 0.2, 2.2, 0.2, 2​.

The total number of elements in the data is $n=4$

Thus, the mean of the given numbers is

$\overline x=\dfrac{ 0.2+2.2+0.2+2}{4}$

  $=\dfrac{4.6}{4}=1.15$

Therefore, the mean of the given numbers is 1.15.
