Answer: |p-72% |≤ 4%
Step-by-step explanation:
Let p be the population proportion.
The absolute inequality about p using an absolute value inequality.:
, where E = margin of error, 
= sample proportion
Given: A poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% .
|p-72% |≤ 4%
⇒ 72% - 4% ≤ p ≤ 72% +4%
⇒ 68% ≤ p ≤ 76%.
i.e. p is most likely to be between 68% and 76% (.
Answer:
THE EQUATION HAS NO SOLUTION!
Step-by-step explanation:
Simplify 1/4 , (1/4 • (20 - 4a)) - (6 - a) = 0 , 3.1 Pull out like factors : 20 - 4a = -4 • (a - 5) , (5 - a) - (6 - a) = 0 , -1 = 0 , 5.1 Solve : -1 = 0, THERES NO SOLUTION MATE TRUST ME!
