We have the given in the problem as mentioned:
A total of 130 students and only 7 had been placed in the wrong math class.
With this given, we can easily draw the proportion of all students who have been placed in the wrong math class by estimation method and the solution is shown below:
Proportion = 7/130
Making a fraction is the easiest way to do this.
The x-intercepts give solutions to a problem that equals zero.

The vertical asymptotes are values x cannot be, in a fraction the denominator can not be zero.

Horizontal asymptotes are the values y approaches. This can be accomplished by making the leading term have a coefficient of 6
3 slices are left because a quarter of the 8 is 2 so there is 6 left than 6-3=3 so 3 slices are left
Answer:
The dependent variable is A
The independent variable is w
Step-by-step explanation:
Given

Required
Identify the variables
In 
The value of w is independent of the value of A.
In other words:
A derive its own value from w; by multiplying 25 and w.
Take for instance:

The value of A would be:


Hence:
The dependent variable is A
The independent variable is w
I’m not sure, but I think you divide 360 by each one of those angles.
