You subtract because it's just adding a negative which cancels out the adding and makes it a subtraction problem.
The correlation coefficient represents a moderate negative correlation is -0.64.
<h2>We have to determine</h2>
Which correlation coefficient represents a moderate negative correlation?
<h3>According to the question</h3>
The correlation coefficient is a measure of the strength of the linear relationship between two variables and is denoted by r.
The values between 0.3 and 0.7 indicate a moderate positive (negative) linear relationship.
The values between -0.3 and -0.7 indicate a moderate negative linear relationship.
The only value of r in the option is r= -0.64 lies in a given interval of the moderate negative linear relationship.
Hence, the correlation coefficient represents a moderate negative correlation is -0.64.

(AB)=100
ABC+CBD=100
4x+2+3x-7=100
7x-5=100
7x=100+5
x=105/7
x=15
(CBD) =3x-7
3(15)-7
