Question

There's a roughly linear relationship between the number of times a species of cricketwill chirp in one minute and the temperature outside. For a certain type of cricket,this relationship can be expressed using the formula I = 0.3lc + 36, where Trepresents the temperature in degrees Fahrenheit and c represents the number oftimes the cricket chirps in one minute. What is the meaning of the I'-value whenc= 148?

Answer 1

The function T = T(c) tells us the temperature based on the number of times c the cricket has chirped in one minute. In other words, if we plug c = 148 in the formula we get:

`\begin{gathered} T(c)=0.31c+36 \\ T(148)=0.31*(148)+36 \\ T(148)=81.88^oF \end{gathered}`

That means if the cricket chirps 148 times per minute, the temperature must be 81.88 ºF.

Answer: The expected temperature in degrees Farenheit if the cricket has chirped 148 times perminute.
