Answer:
The correct answer is x = -6.
Step-by-step explanation:
To solve this problem, we first must use the distributive property on the right side of the equation. This means that we can take the coefficient (the number located on the outside of the parentheses) and multiply it by the terms inside the parentheses. If performed correctly, we get the following:
-20 = -2(4 -x)
-20 = -2(4) - (-2)(x)
-20 = -8 + 2x
Next, we must begin to isolate the variable x on the right side of the equation. To do this, we should begin by adding 8 to both sides to cancel out the -8 on the right side of the equation.
-20 + 8 = -8 + 8 + 2x
-12 = 2x
Finally, we should divide both sides by 2 to get rid of the coefficient of x on the right side of the equation.
-12/2 = 2x/2
x = -6
Therefore, your answer is x = -6.
To check this answer, you could substitute this value back into the original equation and make sure that it produces a true statement.

Answer:
The online survey has large biases concerning representativeness. Regarding the behavioural characteristics of consumers, the face-to-face data delivers the best results, followed by the telephone interviews and finally the online survey.
Face-to-face surveys still deliver the most representative results. Telephone surveys may provide a good alternative, but we would advise use of a larger sample. The online survey needs to be corrected, one should relinquish representativeness.
