Answer:
Step-by-step explanation:
We would assume that a randomly selected registered voter, x is classified as a conservative or not. It means that there are only 2 possible outcomes. Thus, it is a binomial probability distribution and the probability of success, p is that a randomly selected voter is classified as a conservative. Therefore,
p = 20% = 20/100 = 0.2
Number of trials, n = 10
Number of success, x = 6
The probability that six out of 10 would be conservatives is expressed as
P(x = 6)
Using the binomial probability calculator,
P(x = 6) = 0.0056
ANSWER

EXPLANATION
The first equation is

The second equation is

We want to eliminate y, so we multiply the first equation by



We now subtract equation (3) from (2)



Multiply both sides by



Substitute into the first equation to solve for x .

Multiply to obtain



Multiply both sides by 2.


The solution is

Answer:
The real numbers include all the rational numbers, such as the integer −5 and the fraction 4/3, and all the irrational numbers, such as 2 (1.41421356..., the square root of 2, an irrational algebraic number).
At very minimum, move (4/5)x to the other side of the given equation. Then:
-(4/5)x + y = 0.85. This is the equation in standard form.
