What is the mean of the values in the stem-and-leaf plot?

enter your answer in the box.

The answer is:  "42" .

Explanation:

From the stem-and-leaf plot provided, we can write the following values from the data set, from least to greatest:

        {15, 18, 46, 50, 50, 50, 50, 57} ;


To calculate the mean, we take the sum of all the values in the data set; that is, we add up all the values in the data set; and we divide that sum total by the number of values in the data set. 

In our data set, we have EIGHT (8) values.

To calculate the mean:

   
   {15 + 18 + 46 + 50 + 50 + 50 + 50 + 57} / 8 =  the mean {our answer}.

 
        →  {15 + 18 + 46 + 50 + 50 + 50 + 50 + 57} / 8 =

                → {336} / 8  =  42 .

The answer is:  " 42 " .
