Question

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°

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=\(\frac{28}{7}=4\)
