Final answer:
Using Dolbear's Law, the ambient temperature in degrees Fahrenheit is calculated as 56.5 when the Snowy Tree Cricket chirps 66 times per minute.
Step-by-step explanation:
Dolbear's Law describes the relationship between the chirping rate of Snowy Tree Crickets and the ambient air temperature. Given that Dolbear's Law is represented by the formula T = 50 + (N - 40) / 4, we can calculate the temperature in degrees Fahrenheit when N, the number of chirps per minute, is 66.
To solve for T when N = 66:
First, insert 66 into the formula in place of N: T = 50 + (66 - 40) / 4.
Then, calculate the value inside the parentheses: 66 - 40 = 26.
Divide 26 by 4: 26 / 4 = 6.5.
Add this result to 50: 50 + 6.5 = 56.5.
Thus, the temperature T in degrees Fahrenheit is 56.5 when the chirps per minute are 66.
