Answer: The margin of error tells that the proportion of the a random sample women said they do not get enough time for themselves can be differ by ±3% than the estimated proportion (47%)
Step-by-step explanation:
Given : A New York Times poll found that 47% of the women said they do not get enough time for themselves.
The poll announced a margin of error of ± 3% for 95% confidence in its conclusions.
A margin of error gives that value of percentage error of in results by which any random value will differ from the real population value.
Here the margin of error tells that the proportion of the a random sample women said they do not get enough time for themselves can be differ by ±3% than the estimated proportion (47%).
12/6 can be written as 2 because 6 can go into 12 two times.

Answer:
We have the equation:
(14 N/mm)*X = Y N/cm
So we want to transform 1/mm to 1/cm.
We know that:
10mm = 1cm
1 = 10mm/1cm (we want to have mm on the numerator, so it cancelates with the mm in the denominator)
then the conversion is from 1/mm to 1/cm is:
X = 10mm/cm
then we have:
(14N/mm)*(10mm/cm) = 140 N/cm
