C. The sum of any rational number and any irrational number will always be an irrational number.
Explanation: Each time they assume the sum is rational; however, upon rearranging the terms if their equation, they get a contradiction (that an irrational number is equal to a rational number). Since the assumption that the sum of a rational and irrational number is rational leads to a contradiction, the sum must be irrational.
Answer:
D. Any nonzero rational number times an irrational number is irrational.
Explanation: Assume r is nonzero and rational, and x is irrational. If rx = q, and q is rational, then x = q/r, which is rational. This is a contradiction.
Answer:
E. The system of polynomials is almost the same with the system of whole numbers.
Explanation: We count with and use a base 10 (decimal) system. Polynomials such as the function above are a “base x” system.
Answer:
F. Addition, subtraction, and multiplication would all be closed because every answer would be a polynomial. Division is not closed because when we divide numbers, sometimes they don’t divide evenly, leaving us with a remainder, which we can write as a fraction.

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Fwam sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below. 417 visitors purchased no costume. 63 visitors purchased exactly one costume. 7 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase no costume as a decimal to the nearest hundredth.
Answers
Answer:
0.86
Step-by-step explanation:
The probability that the next person will purchase no costume is 36%.
What is probability ?To express the probability that the next person will purchase no costume as a percent to the nearest whole number, we will use the total number of visitors to the website as the denominator and the number of visitors who purchased no costume as the numerator.
The total number of visitors to the website,
168 + 252 + 47 = 467
The number of visitors who purchased no costume = 168.
So, the probability that the next person will purchase no costume is:
168/467 = 0.360
0.3609 × 100
= 36.09
Rounding this to the nearest whole number, we get,
36%

Answer:

Step-by-step explanation:
I took the quiz in the car 100
If we want to make the graph wider, then we must have a horizontal dilation, so the correct option will be 1/4.
How do horizontal dilations work?
A horizontal dilation is a transformation that makes the graph of a function wider.
For a function f(x) an horizontal dilation of scale factor k (with k > 1) is written as:
g(x) = f(x/k)
For the case of the absolute value function we will have:
g(x) = |x/k| = (1/k)*|x|
So we need to find the value (1/k).
Remenber that k > 1, then 0 < (1/k) < 1.
This means that the only values between 0 and 1 could fill the blank in such a way that the graph of that function is wider than the one of the parent function, so from the given options, we will take:
1/k = 1/4
Then the function is:
g(x) = (1/4)*|x|
This function will have a graph wider than the one of f(x) = |x|
