3) The rate at which crickets chirp varies linearly with the outdoor temperature. At 59°F crickets make 76 chirps per minute, and at 65°F they make 100 chirps per minute. a) Write the equation expressing chirping rate, c, in terms of temperature, t. b) Predict the chirping rate for 90°F. c) How warm is it if you hear 120 chirps per minute? d) Calculate the temperature-intercept. Write a sentence explaining what this number tells you about the real world. e) Calculate the chirping rate-intercept. Write a sentence explaining what this number tells you about the real world.
