Correct Answer

B. (Q(7))

Step 1

Concept

In a linear model the midpoint of (2) and (12) is (7). Therefore (Q(2)+Q(12)=2Q(7)).

Step 2

Why this answer is correct

The correct answer is B. (Q(7)). In a linear model the midpoint of (2) and (12) is (7). Therefore (Q(2)+Q(12)=2Q(7)).

Step 3

Exam Tip

रेखीय मॉडल में (2) और (12) का मध्य (7) है। इसलिए (Q(2)+Q(12)=2Q(7)) होता है।
