Question

A poll estimates that 43% of likely voters are in favor of additional restrictions on teenage drivers. The poll has a margin of error of plus or minus 4%. Write and solve an absolute value equation to find the minimum and maximum percent of voters that actually support the restrictions.
Group of answer choices

| x – 43 | = 4; minimum = 43%, maximum = 47%

| x – 4 | = 43; minimum = 39%, maximum = 47%

| x – 4 | = 43; minimum = 43%, maximum = 47%

| x – 43 | = 4; minimum = 39%, maximum = 47%

    Answer: | x – 43 | = 4; minimum = 39%, maximum = 47%

    Step-by-step explanation:

    Given the following :

    Percentage of voters in support of additional restrictions son teenage drivers = 43%

    Margin of Error in polls = ±4 % points

    The absolute value inequality to find the lowest and greatest percent of points :

    X = mid value

    43% = estimated percentage

    ±4= error margin

    Hence,

    |mid value – estimate| = error margin

    |x−43| = 4

    Hence,

    -4 + 43 = 39

    4 + 43 = 47

    39 ≤ x ≤ 47

    Hence,

    Least percentage point = 39

    Greatest percentage point = 47
