Use the dot plot to answer the question.

A dot plot that has 3 dots at 1, 4 dots at 2, 3 dots at 3, 4 dots at 4, 5 dots at 5, & 3 dots at 6.

What is the mean of the data set in the dot plot?

Enter your answer as a number rounded to the nearest tenth, like this: 42.5

The mean of the data set in the dot plot will be: 3.6        

Step-by-step explanation:

Here is the dot plot:

1                 2                3                  4                  5                    6

Dot plot is also attached below.

Mean is basically the average. In order to find the mean, we need to add the numbers and then divide the sum by the number of addends.

Mean = (1+1+1+2+2+2+2+3+3+3+4+4+4+4+5+5+5+5+5+6+6+6)/22

          = 79/22

          = 3.6

Therefore, the mean of the data set in the dot plot will be: 3.6        

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
