These insects often form a chorus at night, singing a high-pitched, two-note song. The approximate temperature in Fahrenheit can be estimated by counting the number of cricket chirps made in one minute, dividing this number by 4, and adding 40. You can use the following formula to find the approximate temperature (F) if you know the number of chirps (N) made in one minute: N — 4 ؉ 40 ‫ ؍‬F 6. A cricket chirps 100 times per minute. Estimate the air temperature. 7. a. About how cold is it when you hear no cricket chirps?
