Could use some help please and thank you quickly tho it’s timed
andriy [413]

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

Anna007 [38]

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.

\textsf{Average of Online customers}=\dfrac{ 1 \times 3+ 4 \times 4+ 5\times 5}{10}=4.4

\textsf{Average of Walk-in customers}=\dfrac{ 3 \times 1+ 6\times 2+ 1\times 3}{10}=1.8

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.
