Answer:
d. each trial has exactly two outcomes whose probabilities do not change
Step-by-step explanation:
A binomial experiment is one where there are exactly two outcomes for each trial and probability for getting success is constant in each trial.
In other words, each trial is independent of the other.
The trials need not be continuous nor time between trials to be constant.
Since trials are to be independent, each trial cannot influence the next.
Only option d is right.
d. each trial has exactly two outcomes whose probabilities do not change
Examples are tossing of coins, throwing dice, drawing cards or balls with replacement, etc
First isolate the "y" in the equation.
2y - x = -12 Add x on both sides
2y - x + x = -12 + x
2y = -12 + x Divide 2 on both sides to get "y" by itself
Your slope is 
.
For the equation of the line to be parallel to the given equation, the slopes have to be the same. So the parallel line's slope is also
y = mx + b
To find "b", you plug in the point (18,2) into the equation
2 = 9 + b Subtract 9 on both sides
2 - 9 = 9 - 9 + b
-7 = b
Your equation is:
Answer:
The coordinates of point B are : (-1, 1)
Step-by-step explanation:
You multiply -4 by 2 which gives you -8 then you multiply 1 by 2 which gives 2.
Then you create the equations 
you substitute -7 for +7 and add 7 to -8 which gives -1 (
) and subtract 1 from 2 which gives you 1 (
)
To check your answer use the midpoint formula 
which gives you your midpoint (-4,1)
It’s an irrational number
