Question

theres a roughly linear relationship between the number of times a species of cricket will chirp in one minute and the temperature outside, as expressed in the graph below. what is the meaning of the ( x ) - value when ( y = 80 )?
answer
the expected temperature in degrees fahrenheit if the cricket has chirped 80 times per minute.
the number of times the cricket could be expected to chirp in one minute if its ( 80^{circ}f ).
the number of times the cricket could be expected to chirp in one minute if its ( 172^{circ}f ).
the expected temperature in degrees fahrenheit if the cricket has chirped 172 times per minute.

Explanation:

In a linear relationship graph where \(x\) - axis represents "Chirps Per Minute" and \(y\) - axis represents "Temperature (Degrees Fahrenheit)", when we are looking for the \(x\) - value when \(y = 80\), we are essentially finding the value of the independent variable (\(x\)) for a given value of the dependent variable (\(y\)). Since \(x\) is Chirps Per Minute and \(y\) is Temperature, the \(x\) - value when \(y = 80\) gives the number of times the cricket could be expected to chirp in one minute if it's \(80^{\circ}\text{F}\).

Answer:

The number of times the cricket could be expected to chirp in one minute if it's \(80^{\circ}\text{F}\).
