Answer:
Sampling Error
Step-by-step explanation:
When the researcher randomly selected 200 people, he is creating an sample or subset from the population, that would be all the people in the earth. The error obtained was product of the fact that the analysis he made was estimated from the sample and not the whole population. There is no other mentioned factor that could cause an error, so the answer would be a sampling Error.
Substitute y = -2x + 4 into 7y = -14x +28
7y = -14x +28
7(-2x + 4)= -14x +28
-14x + 28 = -14x +28
0 = 0
answer
infinitely many solutions

Answer:
y = 8x + 4(6)
y = 8x + 24
Step-by-step explanation:
8 friends bought tickets to a hockey game at $x
4 of them also bought a guide book at $6
If y = total cost
8 people bought tickets and 4 bought guides.
Then simplify by multiplying 4 and 6.
No 2 times 4 is 8 and 3 times 3 is 9, 8 plus 9 is not 33 it’s 17
