Answer:
Margin of error is 4.1
Step-by-step explanation:
The margin of error in statistics refers to a quantity which expresses the amount of random sampling error from the results of a survey conducted. A large margin of error implies less confidence in the results of the survey.
The margin of error can be approximated using the population standard deviation, if known.
Therefore, the margin of error will be reported as 4.1

Answer:
{-14, 4}
Step-by-step explanation:
the absolute value function only makes sure that the result always has a positive sign.
so, (x + 5) must be either +9 or -9 to make the original equation true. the absolute value would turn both into +9.
so,
x + 5 = 9
x = 4
and
x + 5 = -9
x = -14
that gives us the correct set of solutions as indicated above.
