Question

The formula f= n/4 + 37 estimates the temperature F in degrees Fahrenheit when crickets chirp n times per minute. Use the formula to estimate the temperature when n = 120 chirps/min. round to the nearest whole number if necessary. A.63°FB.68°FC.72°FD.67°F

Answer 1

The formula for estimating the temperature F in degrees Fahrenheit when crickets chirp n times per minute is expressed as

f = n/4 + 37

Given that n = 120,

f = 120/4 + 37

f = 30 + 37

f = 67

The correct option is D
