Question

A pool estimate that 43% of likely voters are in favor of additional restrictions on teen drivers the Poll has a margin of error of plus or minus 4%. Write and solve the absolute value equations to find the minimum and maximum percent of voters that support the restriction

Answer 1

Kindly check explanation

Explanation:

Given that :

Estimated number of voters in favor of additional restriction = 43%

Margin of Error = ±4%

Write and solve the absolute value equations to find the minimum and maximum percent of voters that support the restriction:

Minimum percentage of voters = 4% lesser than the estimated number of voters

Maximum percentage of voters = 4% greater than the estimated number of voters

Let number of voters = v

|v - 43%| = ±4%

v = - 4% + 43% = 39% = minimum percentage

v = +4% + 43% = 47% = maximum percentage

39% ≤ v ≤ 47%
