The equation in slope intercept for is y = 5/2x + 4
The y intercept is 4
Its C! Lets say x=30
|30-323|=50
This could technically be true because it would show if the temp is within range
I believe it is D, stratified random sampling.
Hope this helps!!
4.0081 x 10 to the 4th power. I know because I did this one.
