Answer:
Part A) The polynomial has three terms
Part B) The terms are 
Part C) Is a 2nd degree polynomial
Part D) The name of the polynomial is a 2nd degree trinomial
Step-by-step explanation:
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
we have

The polynomial has three terms
The terms are

therefore
The polynomial is a trinomial
The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).
The term is 
The highest exponent is the 2 so this is a 2nd degree polynomial
therefore
The name of the polynomial is a 2nd degree trinomial
Answer:

Step-by-step explanation:
Okay, to do this we must understand what parallel means.
parallel means that that one line will NEVER touch the other. In order for this to happen they must be increasing (or decreasing) by the SAME rate. I.e the slope of your line must be the same as the lin in question thus our equation looks like,
.
Now lets find
.
To do this, plug the point (3,6) into the equation
6=4(3)+C
6=12+C
-6=C
Thus now that we know C, our equaiton is

Answer:
98.01% probability of getting 5 clean sheets
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, the order that the sheets are chosen is not important, so we use the combinations formula to solve this problem.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

0.4% of the sheets contain spots
Of 500, that is 0.004*500 = 2.
What is the probability of getting 5 clean sheets although 0.4% of the sheets contain spots?
Desired outcomes
2 are defective, so 5 sheets from a set of 500 - 2 = 498.

Total outcomes
5 sheets from a set of 500.

Probability:

98.01% probability of getting 5 clean sheets
