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".
Also the question itself is kinda judging and comparative
so overall, umm... this question isn't really good
hope this helps :D
The mean of the answer is 20.5 because you add all of the number together and divide by 6 because there's 6 numbers.
I'm sorry, but I don't know how to do the standard deviation...
Hope this helped!
Answer:
The answer is;
4^3/10 • x^9/10 •y^3/5
Step-by-step explanation:
We want to express the expression in the bracket in radical form;
(4x^3y^2)^3/10
What we shall do here is to multiply all the powers of the terms in the bracket by 3/10
So we shall have;
4^3/10 • x^(3*3/10) * y^(2*3/10)
= 4^3/10 • x^9/10 • y^3/5
Answer:
137.12
Step-by-step explanation:
Density = mass/volume
Density = 3.51
Mass = 481.3
Thus: 481.3/3.51 = 137.122507123
