Step-by-step explanation:
it is unbiased because the people are chosen at random
For a solution of 'all real numbers' to occur, you must end up with a statement that is true no matter what
example
simplifying results in x=x or 8=8 or 0=0 or something liek that
an example equation would be 2(x+1)=2x+2, simplifies to x=x or 2=2 or 0=0
no solution is when you get a false statement from simplifying
example, 3=4 or -1=0
an example equation could be 2(x+1)=2x+3, it simplifies to 2=3 which is false
Answer:
11
Step-by-step explanation:
Answer:

Step-by-step explanation:
We know that we are dealing with parallel lines, as there are double headed arrows on each of the lines, pointing in the same direction.
This means we can use corresponding / alternate angle laws.
We know that the angles on a straight line add up to
, so we can solve for the angle just above the
to try and see if that will help us.
(Our angle, added to another angle we don't know yet is 180)
Solve for 

We can now apply the corresponding angle law, (as we have an 'F' shape), to determine that:
