Apolitical polling agency predicts candidate a will win an election with 54% of the votes. their poll has a margin of error of 4% both above and below the predicted percentage. which inequality represents the predicted possible percent of votes, x, for candidate a?

The correct answer is:

50 ≤ x ≤ 58

Explanation:

Since the margin of error goes above and below the predicted percentage, to find the lower end of the inequality, we subtract the margin of error from the prediction:

54-4 = 50%

To find the upper end, we add the margin of error to the prediction:

54+4 = 58%

This means that x lies between 50 and 58, or 50≤x≤58

d. all of the above
