The simplified polynomial is; xy(x²y - xy² +1) and; the value when x=-3 and y=2 is; -186
From the polynomial given;
The polynomial can be factorised to yield a simpler form as follows;
This is so because, xy is a common factor.
The value is therefore;
- (-3×2)((-3)²2 - (-3×2²) +1)
= -186

Using conditional probability, it is found that there is a 0.8462 = 84.62% probability that a woman who gets a positive test result is truly pregnant.
<h3>What is Conditional Probability?</h3>
Conditional probability is the probability of one event happening, considering a previous event. The formula is:

In which
- P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem, the events are:
- Event A: Positive test result.
The probability of a positive test result is composed by:
- 99% of 10%(truly pregnant).
Hence:

The probability of both a positive test result and pregnancy is:

Hence, the conditional probability is:

0.8462 = 84.62% probability that a woman who gets a positive test result is truly pregnant.

Answer:
Step-by-step explanation:
I believe if you multiply 850×2= 1700.
Multiply 850×3..
That would equal to 2550.
The two answers would 4/12 and 9/12. This is because one third of 12 is 3 and three fourths of 12 is 9.
Answer=Order of operations
The order of operations (which we use PEMDAS to help us remember) tells you which operation to do first.
