The data she would collect would be grouping people depending on how much video games they played.
This however, is not a statistical question. Instead, she should set for example: 1-3 hrs per week, 4-6 hrs, etc. People play different amounts of hours, and so you cannot set a specific number, it must be a "range-of-numbers".

so overall, umm... this question isn't really good
hope this helps :D
The answer is none. There are no solutions
Answer:
(4,1)
Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :)
X ∈ (real numbers symbol not in brackets) : 0<x<17.89 and 18.61<x
In the standard form of quadratic

the discriminant is

In your quadratic, a = 1, b = -9 and c = -10
Now you need to plug these values into the expression for the discriminant.
