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 " .
