Answer:
Step-by-step explanation:
Given is an algebraic polynomial of degree 5.

Here leading term is p=3 and constant term is q =12
Factors of p are ±1,±2,±3
Factors of q are 
Possible forms of p/q will be the same for any other polynomial of degree 5 with leading term =3 and constant term = 12
Hence any other polynomial

will have same possible zeroes of p/q, when a,b,c are rational.
Hence any polynomial of this type would have the same possible rational roots.
I don't know what you are talking about please re word the question its really hard to understand what your asking.
Answer: 13300
========================================
Work Shown:
A = event that it rains
B = event that it does not rain
P(A) = 0.30
P(B) = 1-P(A) = 1-0.30 = 0.70
Multiply the attendance figures with their corresponding probabilities
- if it rains, then 7000*P(A) = 7000*0.30 = 2100
- if it doesn't rain, then 16000*P(B) = 16000*0.70 = 11200
Add up the results: 2100+11200 = 13300
This is the expected value. This is basically the average based on the probabilities. The average is more tilted toward the higher end of the spectrum (closer to 16000 than it is to 7000) because there is a higher chance that it does not rain.
Step-by-step explanation:

Take the reciprocal of the second term and multiply. This leaves you with 5/10•2/3.
5/10 can be simplified into 1/2, leaving you with 1/2•2/3 multiply the numerators and denominators separately, and get 2/6, which simplified to 1/3.
1/3 is the quotient.
