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.
Answer:
Step-by-step explanation:
Volume = πr²h/3 = πr²9/3 = 3πr²
3πr² = 3πy² + 30πy + 75π
r² = y² + 10y + 25
r² = (y+5)²
r = y+5

Answer:
(x-5) (x-2)
Step-by-step explanation:
x^2 (-2x-5x) +10
basically you will write the equation down and then to double check multiply the x and then the -5 into (x-2). this can be repetitive if you get it wrong so try to do numbers that make sense.
