Final answer:
The value of r is 3 when s is 9. The correct answer is 3.
Step-by-step explanation:
A linear relationship between the quantities represented by the variables s and r is a relationship where one variable increases or decreases proportionally with the other variable. The correlation coefficient, r, measures the strength and direction of this linear relationship. A positive value of r indicates a positive correlation, where both variables increase or decrease together. A negative value of r indicates a negative correlation, where one variable increases while the other decreases.
The values of s increases multiple of 3 and values of r are the "sum of two values of s - previous value of r".
When s=9 , r=3 .
Hence, option "r=3" is correct one
