Answer:
[tex]4850 \leq x\leq 5150[/tex]
Step-by-step explanation:
The 3% accuracy represents a margin of error, which offers an interval about the possible outcomes. In other words, the results can be in a range from -3% to 3%.
If 5,000 people would vote for the candidate with a 3% of accuracy, it meas the results are in the interval
[tex]5,000-0.03(5,000)\leq v\leq 5,000+0.03(5,000)[/tex]
Where the minor value is without the 3% and the greatest possible is with 3%.
Therefore, the combined inequality is
[tex]5000-150\leq x\leq 5000+150\\4850 \leq x\leq 5150[/tex]
Which means the accuracy of the survey states that from 4,850 to 5,150 people would vote for candidate A.
