Answer: D. -1.2 Degree Fahrenheit.
Step-by-step explanation:
Since,
\(\text{ The average daily changes } =\frac{\text{ Total changes}}{\text{ Number of days}}\)
Here,
The total changes = - 16.8° F ( - sign shows the decreasing )
And, the number of days = 14
Hence,
\(\text{ The average daily changes } =-\frac{16.8}{14}=-1.2\)
⇒ The average daily rate of change in the high temperature in degrees Fahrenheit is -1.2° F.
