The given study is observational study
To gauge how strongly two variables are related to one another, correlation coefficients are used.
A statistical indicator of the strength of the association between the relative movements of two variables is the correlation coefficient. The values are in the -1.0 to 1.0 range. There was a measurement error in the correlation if the estimated value was larger than 1.0 or lower than -1.0. Perfect negative correlation is shown by a correlation of -1.0, and perfect positive correlation is shown by a correlation of 1.0. A correlation of 0.0 indicates that there is no linear link between the two variables' movements. Finance and investing can benefit from the usage of correlation statistics.

The answer is 5.
You just plug whatever number is in the f(?) part in for x!
It would be: -12 + 15x = 3(-4+5x)
So, after common factor out, your answer is 3(-4+5x)
Hope this helps!
Answer:
5^2=25 5x5
5^-2=.04 The reciprocal of 5 is 1/5 ^2 means that 1/5 x2 = 2/5 or .4
(-5)^2=25 -5*-5
-5^2=-25 -(5*5)
