Math 9 Final Review 2017


The difference between these two numbers is that the one on the bottom will be an even number where the top number will still be negative.




if the negative is outside the brackets and the exponent is negative then the answer will be negative.


11.4 misleading statistics

This would effect people in a way that people with fake accounts or have fake news, would persuade people into things that are not true. Also sometimes fake accounts might want to target in things you like so they monitor your searches and stuff like that, after they know what you like then they will know whether to bother you or not. all fake accounts have goals in what they are trying to do, some try to make you like something, some make you try to do something, but in the end all they want is your feedback, fake news is almost like someone saying lays is the best chips brand and then posting it on social media after a couple months then you would get lots of feedback which is exactly what the person wants. After seeing fake news it makes you believe them because they are presenting it as if the news is true, so this makes you doubt your thoughts and just go with what the majority of the people want.This is how fake accounts and fake news would affect people.


  • I believe statistics are a great way to find out what you need, but people need to understand if you only survey 10 people then you could have had a bunch that are unbalanced where if you did up to maybe 1000 people then it would be a lot more balanced for the results.


  • I learned that statistics are pretty much how we find out what people like and dislike, for example how would we know that people like steak or chicken, how did we find out that is my point most things in life are made up of statistics, is this reliable though, it is to some extent, people have gotten lazy and started to minimize the people who are being asked, so this brings controversy because you do not know if the results are correct.


  • Some problems like i already stated above is that when you start to minimize the people who are being asked you do not know the whole populations idea because if you get the whole results you will have the answer and you will know for sure that it is correct, but like i said when you minimize it you will not get the whole populations idea.

Adding or subtracting Intagers

a) 5 + 11= 16


b) -5 + (-11) = -16


c) -5 – (-11) = 6


d) 5 – 11 = -6


e) 5 – (-11) = 16


f) -5 – 11 = -16


g) -5 + 11 = 6


A and E, B and d, C and G are equivalent.  These equations have the same answers because  they were different too begin with, the zeros were added which made the answers the same.

This activity helped me understand integers a lot more, and figure out how they wor
