Question

a researcher studied the relationship between the number of times a certain species of cricket will chirp in one minute and the temperature outside. her data is expressed in the scatter plot and line of best fit below. what is the meaning of the y - value on the line when ( x = 120 )?
answer
the predicted temperature in degrees
fahrenheit if the cricket has chirped 120
the predicted temperature in degrees
fahrenheit if the cricket has chirped 70.8
the actual temperature in degrees fahrenheit
when the cricket has chirped 70.8 times.
the actual temperature in degrees fahrenheit
when the cricket has chirped 120 times.

Explanation:

In a scatter - plot with a line of best fit, the line represents a predicted relationship. The \(x\) - axis is "Chirps Per Minute" and the \(y\) - axis is "Temperature (degrees Fahrenheit)". When \(x = 120\) (where \(x\) is the number of chirps per minute), the \(y\) - value on the line of best fit gives a predicted value (not an actual value, since actual values are the scatter points). So it is the predicted temperature in degrees Fahrenheit if the cricket has chirped 120 times.

Answer:

The predicted temperature in degrees Fahrenheit if the cricket has chirped 120 times.
