Answer 1

The approximate average low temperature in Marsh City is 0 F.

Explanation:

The formula of average is:

`average = (a_(1)+a_(2)+a_(3).....a_(n) )/(n)`

where n is the number of samples. For this case n=7.

Substituting in the formula:

`average = ((-3)+ (-5) + 3+ 7+ 2+ 2+ (- 5))/(7)`

`average = (1)/(7)`

`average = 0.143 F = 0 F (rounding)`
