Question

Biologists have noticed 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 111 chirps per minute at 69degrees F and 171 chirps per minute at 90 degrees F. (a) Find a linear equation that models the temperature T as a function of the number of chirps per minute N. T =_____________??? (b) What is the slope of the graph??? __________slope? What does it represent? The slope means that the temperature in Fahrenheit degrees increases___________??? as rapidly as the number of cricket chirps per minute. (c) If the crickets are chirping at 156 chirps per minute, estimate the temperature. (Round your answer to the nearest whole number.) ____________Fahrenheit ???

Explanation / Answer

Let equation be

y = mx+c

111 = 69m+c

171 = 90m+c

m = 20/7, c = -603/7

b) y = (20/7)x-(603/7)

Slope = 20/7
