A clock has 12 hours on it.
360/12 = 30
Each hour is 30 degrees.
3pm to 7:30pm is 4.5 hours
Multiply total hours by degrees per hour:
4.5 x 30 = 135 degrees
That is 2 of the y^2
that means 2y^2 aka 2 times y^2
Negative correlation refers to an inverse relationship between two variables. When one variable increases, the other decreases.
The variables are latitude and average temperature.
The explanatory variable is latitude and the response is the average temperature. Choice B.
As the latitude increases, the average temperature decreases. This is a strong negative correlation of between the two variables.
