Question

Dolbear's law states the relationship between the rate at which Snowy Tree Crickets chirp and the air temperature of their environment. The formula is Upper T equals 50 plus StartFraction Upper N minus 40 Over 4 EndFractionT=50+ N−40 4​, where T is a temperature in degrees Fahrenheit and N is a number of chirps per minute. If Nequals=8282​, find the temperature in degrees​ Fahrenheit, T.

Answer 1

The temperature would be 60.5°.

Substituting this into our formula, T = 50+(N-40)/4, we have

T = 50+(82-40)/4 = 50+42/4 = 50+10.5 = 60.5
