3. Correlation coefficients can be represented by the variable r
Step-by-step explanation:
Correlation coefficients show if there is a strong or weak positive or negative relationship, or if there is no relationship between the variables.
Correlation coefficients are negative when the relationship is inversely proportional and positive when the relationship is proportional.
Correlation coefficients can be any value less than or equal to 1 or greater than or equal to -1.
Step-by-step explanation:
start by setting each equation to each other

first we are going to subtract 2x from both side of the equation

now subtract 1 from both sides

now divide by -3 on both sides
X^2 + X - 12 = 0
(X + 4)(X - 3) = 0
X = -4 and X = 3.
You would get 2015.17568 as the interest rate i believe
