Question

Dolbear’s law states the relationship between the rate at which snowy tree crickets chirp and the air temperature of their environment. Formula 50+ n-40 over 4 Where t is a temperature degrees Fahrenheit and N is a number of chirps per minute. If n=74 find the temperature in degrees Fahrenheit,T

Answer 1

Given data:

N=74

Equation:

$T=50+\frac{N-40}{4}$

To find the temperature T given N=74 substitute in the equation the N by 74 and evaluate to get the corresponding value of T:

$\begin{gathered} T=50+\frac{74-40}{4} \\ \\ T=50+\frac{34}{4} \\ \\ T=50+8.5 \\ \\ T=58.5 \end{gathered}$Then, in N=74 the temperature in degress Fahrenheit is 58.5°F
