Answer:

-2°F

Step-by-step explanation:

The average low temperature on January 1st is an arithmetic mean.

It is equal to the sum of all low temperatures on January 1st divided by the number of January 1st for 5 years.

Therefore, the average low temperature on January 1st

= [tex]\frac{2 + (-10) + 7 + 4 + (-13)}{5}[/tex]

= [tex]\frac{-10}{5}[/tex]

= -2 (°F)
