Answer:
The approximate average low temperature in Marsh City is 0 F.
Step-by-step explanation:
The formula of average is:
[tex]average = \frac{a_{1}+a_{2}+a_{3}.....a_{n} }{n}[/tex]
where n is the number of samples. For this case n=7.
Substituting in the formula:
[tex]average = \frac{(-3)+ (-5) + 3+ 7+ 2+ 2+ (- 5)}{7}[/tex]
[tex]average = \frac{1}{7}[/tex]
[tex]average = 0.143 F = 0 F (rounding)[/tex]
