Sorry I have made an error, here are the right percentages: Republicans: 42.70% Democrats: 32.85% Independent: 38.53%
Michele_Laino
  • Michele_Laino
hint: what is: \(42.7+32.85+38.53=...?\) namely the sum of the above percentages
Howard-Wolowitz
  • Howard-Wolowitz
114.08
Michele_Laino
  • Michele_Laino
is it possible to get a percentage greater than 100 % ?
Howard-Wolowitz
  • Howard-Wolowitz
no but thats what that add up to?
Howard-Wolowitz
  • Howard-Wolowitz
am i not right?
Michele_Laino
  • Michele_Laino
please wait...
Howard-Wolowitz
  • Howard-Wolowitz
ok
Michele_Laino
  • Michele_Laino
we have 423 people under 30, and so we get the subsequent percentages: percentage of republicans people under 30 is: \((196/423)⋅100=...\%\) percentage of democrats people under 30 is: \((138/423)⋅100=...\%\) percentage of independent people under 30 is: \((89/423)⋅100=...\% \)
Michele_Laino
  • Michele_Laino
I think that it is what we can say about political party for people under 30
Howard-Wolowitz
  • Howard-Wolowitz
were gonna be getting decimals here
Howard-Wolowitz
  • Howard-Wolowitz
the first one is 46.33
Michele_Laino
  • Michele_Laino
please keep in mind that they are percentages
Michele_Laino
  • Michele_Laino
correct!
Howard-Wolowitz
  • Howard-Wolowitz
so basically 42.70% is wrong for the answer? of my second question and the correct answer is 46.33%
Howard-Wolowitz
  • Howard-Wolowitz
doing these how are we gonna gt the answer to this

please note that the first percentages refer to whole people, whereas the second ones refer to people under 30
Michele_Laino
  • Michele_Laino
oops.. refer to all people not whole people
Howard-Wolowitz
  • Howard-Wolowitz
ok i see .. again im sorry but i am confusing myself here
Michele_Laino
  • Michele_Laino
furthermore, we can observe this: since the first percentage about democrats is 32.85, whereas the second percentage is 32.6, then we can say that democrats party is composed by almost people under 30
Michele_Laino
  • Michele_Laino
namely the major part of democrats people is under 30
Howard-Wolowitz
  • Howard-Wolowitz
so your saying that it would be major part of democarts is under 30
Michele_Laino
  • Michele_Laino
yes!
Howard-Wolowitz
  • Howard-Wolowitz
do you think that my teacher would understand that for an answer?
Michele_Laino
  • Michele_Laino
I think so, since it is logically correct!
Howard-Wolowitz
  • Howard-Wolowitz
ok sweet.
Michele_Laino
  • Michele_Laino
ok! :)
