Answer:

5) The midrange is 19.5ºF

6) The midrange is 67.5º

Explanation:

The problem tell us how to calculate the midrange.

In (5) the minimum and maximum values are given (-6ºF and 45ºF, respectively). Using the formula:

$Midrange=\frac{-6+45}{2}=\frac{39}{2}=19.5ºF$

In (6), we need to find the minimum and maximum values from a list of them. We can see that the minimum is 58º and the maximum 77º

Then:

$Midrange=\frac{58+77}{2}=\frac{135}{2}=67.5º$
