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 temperature in degrees Fahrenheit to be when there are 20 chirps per second?

Answer:

85 °F


Step-by-step explanation:

The trend line equation is given by  [tex]y=3x+25[/tex]

Where,

  • [tex]x[/tex] is the number of chirps per second, and
  • [tex]y[/tex] is the temperature in degrees Fahrenheit

We want to find the temperature when the number of chirps is 20. So we plug in 20 into [tex]x[/tex] and figure out [tex]y[/tex] :

[tex]y=3x+25\\y=3(20)+25\\y=60+25\\y=85[/tex]
