Answer:
For now, I could tell you that it is not expected a numerical prediction based on experimental measurements to be exact. There are always experimental mistakes that add error to the numerical predictions, not only attributed to the one doing it, but also to the equipment used.
For instance, when a compound is weighed on a balance you should always notice it has uncertainty (e.g. +-1 kg), this means that if the balance says 40 kg, the weight could be between 39 and 41 kg.
Regarding the second question, when you add more values with the same experiment, you can obtain an average value and the most important thing, a deviation that would allow you to include your result in a range.
For the last question, I would need more context.
Have a nice day.
Explanation:
The true statement here is :
c. Teens will tend to start smoking if they believe that it is okay to smoke
Explanation:
The rest of the statements here have amounts of truth in them too. IT is seen that authoritative environments lead children to rebel and become smokers but it is no way the only way people start smoking.
The age for smoking varies too from culture to culture. IT is usually in the age that kids start going out frequently that they start to smoke.
Lastly it is to be seen if the culture that the children live in actually recognizes smoking as legitimate or part of the culture, then they have a high chance of becoming smokers.

Sharecropping was a labor system in which one person and their family grew crops for a large landowner. The landowner would allow them to purchase tools, fertilizer, seed, etc... on credit and when the crop was harvested, the sharecropper would receive a "share" of the crop. Often it was not enough to pay off their credit and the cycle began again. Often known as another form of slavery, but 2/3 of sharecroppers were white.
The reason this leads to a conflict of interest, is because allowing politicians the power of redistricting creates a gateway for partisan gerrymandering, which is the act of manipulating the boundaries of an electoral constituency in order to ensure that a party wins seats in specific district.
