There is a positive correlation between the number of times the striped ground cricket chirps per second and the temperature in degrees fahrenheit. if a scatter plot is made with the number of chirps on the horizontal axis and the trend line is found to be y = 3x + 25, then what would you predict the number of chirps per second to be when the temperature is 55 degrees fahrenheit?

As per the statement:

If a scatter plot is made with the number of chirps on the horizontal axis and

the trend line is given by:

             ....[1]

where,

y represents the temperature in degrees Fahrenheit

x represents the number of chirps per second.

We have to find  the number of chirps per second to be when the temperature is 55 degrees Fahrenheit.

Substitute y = 55 degree Fahrenheit in [1] we have;

Subtract 25 from both sides we have;

Divide both sides by 3 we have;

10 = x

or

x = 10

Therefore, the number of chirps per second to be when the temperature is 55 degrees Fahrenheit is, 10
