Question

Customer feedback ratings for 2 regions is given:


The correct equation representing the average of both the surveys is .

• A. y = $-\frac{1}{3}$x + 14
• B. y = -2x + 58
• C. y = $-\frac{2}{3}$x +116
• D. y = -x + 58

Answer 1

The correct option is D y = -x + 58

Given: Data collected from the suverys.

Average of regions 1 & 2 is:
y = $\frac{(-\frac{4}{3}\text{x}+51-\frac{2}{3}\text{x}+65)}{2}$
= $\frac{-\frac{6}{3}\text{x}+116}{2}$
= -x + 58

Hence, the equation representing the average of both the equations is
y = -x + 58.
