Crickets and Temperature Biologists have observed that thechirping rate of crickets of a certain species is related to temperature, and the relationship appears to be very nearlylinear. A cricket produces 120 chirps per minute at 70F and168 chirps per minute at 80F.(a) Find the linear equation that relates the temperature t andthe number of chirps per minute n.(b) If the crickets are chirping at 150 chirps per minute,estimate the temperature.

Question

Crickets and Temperature Biologists have observed that the
chirping rate of crickets of a certain species is related to temperature, and the relationship appears to be very nearly
linear. A cricket produces 120 chirps per minute at 70F and
168 chirps per minute at 80F.
(a) Find the linear equation that relates the temperature t and
the number of chirps per minute n.
(b) If the crickets are chirping at 150 chirps per minute,
estimate the temperature.
