Respuesta :

from the question;

we are given the following numbers

[tex]12,\text{ 1 , 15},\text{ 21, 4, 5, 31, }9,\text{ 8, 11}[/tex]

we are to find the range of the numbers

but range is defined as

[tex]\text{Range = Highest value - Lowest value}[/tex]

From the numbers

[tex]\begin{gathered} \text{Highest value = 31 } \\ \text{Lowest value = 1} \end{gathered}[/tex]

Therefore

[tex]\begin{gathered} \text{Range = 31 - 1} \\ \text{Range = 30} \end{gathered}[/tex]

Therefore,

The range of the numbers is 30
