Answer:
option c)
d = 1
Step-by-step explanation:
Given the equation in the question,
-3d / (d² - 2d - 8) + (3 / d-4) = (-2 / d+2)
quadratic factorisation
-3d / (d+2)(d-4) + (3 / d-4) = (-2 / d+2)
-3d / (d+2)(d-4) = (-2 / d+2) - (3 / d-4)
taking LCM on right side
-3d / (d+2)(d-4) = ( -2(d-4) - 3(d+2)) / (d+2)(d-4)
canceling (d+2)(d-4) on both sides
-3d = -2(d-4) - 3(d+2)
-3d = -2d + 8 - 3d - 6
-3d + 2d + 3d = 8 - 6
2d = 2
d = 1
Answer:
Online customers buy an average of 4 packs compared with walk-in customers, who buy an average of 2 packs.
Step-by-step explanation:
Create the dot plots (see attached diagrams)
Online customers: blue dots
Walk-in customers: red dots
To calculate the average packs both groups of customers buy, sum all data values and divide by the total number of data values.


Online: 4.4 rounds down to 4
Walk-in: 1.8 rounds up to 2
Therefore, online customers buy an average of 4 packs compared with walk-in customers, who buy an average of 2 packs.
