question 1 of 5 for the first 7 days of january, the daily low temperatures for burlington were 20°,14°,9°,8°,-8°,-11°, and -4° fahrenheit. what was the average daily low temperature, in degrees fahrenheit, for those 7 days? a -1° b 0° c 1° d 4°

Answer

Explanation:

Step1: Find sum of temperatures

Sum = (20 + 14+9 + 8+( - 8)+( - 11)+( - 4)) [ \begin{align*} &20+14 + 9+8-8 - 11-4\ =&(20 + 14+9+8)+(-8-11 - 4)\ =&51+( - 23)\ =&28 \end{align*} ]

Step2: Calculate average

Average=(\frac{\text{Sum}}{\text{Number of days}}), number of days (n = 7) Average=(\frac{28}{7}=4)
