Question

A political 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?

Answer 1

Let P = percent of votes candidate A will have

It is predicted that the candidate will have 54%

Since there is a margin of error of 4% both above and below the predicted percentage

54 – 4 < P < 54 + 4

50 < P < 58

Explanation:

Answer 2

Answer would be 50%≤x≥58%
