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 thetemperature when n = 39 chirps/min. Round to the nearest whole number, if necessary.A.44°FB.46°FC.47°FD.50°F

Answer 1

We have an equation F(n) and we want to know the value when n=39.

To do that, we replace n with 39 in the equation:

`F=(n)/(4)+37=(39)/(4)+37=9.75+37=46.75\approx47`

The value of the temperature for n=39 is 47 °F (Option C)
