The poll has an error of 600 votes. The total number of votes including the error shown by the poll is 15600 or 14400.
Statement B is correct.
<h3>What is the percentage?</h3>
A percentage can be defined as a relative number that shows the hundredth part of the given number. The percentage is represented by the sign "%".
Given that In the next election, 15,000 people will actually vote for Candidate A. A poll has a percent error of 4%.
The error can be calculated as given below.
The poll has an error of 600 votes. This will affect the total number of votes in the election.
The total number of votes V including errors are given as,
<em />
<em />
or
Hence we can conclude that the total number of votes including the error shown by the poll is 15600 or 14400. Statement B is correct.

Answer:
When the online site surveyed about how many times per week the user plays any video game online, the mean was 154. When Thomas surveyed individually to first 50 persons, he got the mean 20.
Now, if Thomas wants that his statistical results should be more accurate and inline than the statistical results, he need to increase the samples Like 100-200 people. As the sample increases, the statistical results are more accurate.
Answer:
See below.
Step-by-step explanation:
A. the area is the square of the length of a side.
Area = (3x - 6)^2
= 9x^2 - 18x - 18x + 36
= 9x^2 - 36x + 36 (answer).
B. The above answer is a polynomial (trinomial) , degree 2.
C. It demonstrates that when we multiply 2 polynomials the answer is also a polynomial.
You have to use carefully Venn Diagram to solve this problem:
n, here below means number of students
GIVEN
----------
n(Cigarettes) = 645
n(Alcohol) = 859
n(Drugs) = 207
n(Alcohol ∩ Cigarettes) = 397
n(Alcohol ∩ Drugs) = 109
n(Alcohol ∩ Cigarettes ∩ Drugs) = 85
And 274 Students "Clean from any of the above"
Let x be the unknown number, that is n(Cigarettes ∩ Drugs)
Start by drawing 3 intersecting circles, one for Alcohol, another for Cigarettes and the 3rd for Drugs:
1) n( Alcohol ONLY) =859-397-109-85 = 268 (only Alcohol)
2) n( Cigarettes ONLY) =645-397-85 - x= 163 - x (only Cigarettes)
3) n( Drugs ONLY) =207- 109 -85 - x = 13 - x (only Drugs).
(Remember that there are 274 Students clean, not shown in Venn)
Total of students (we need it to solve):
TOTAL n(STUDENT) = Alcohol Alone+ Cigarette Alone+ Drug Alone + 274
TOTAL n(STUDENT) = 268 + (163-x) + (13-x) + 274
TOTAL n(STUDENT) = 718 -2x
(hope you can get the TOTAL n(STUDENT) to be able to find x, which is the
n(Drugs ∩ Cigarettes)
This is a permutation problem in which you are to arrange the objects and the order doesn't matter. You can easily calculate it using your scientific calculator. Just use the formula nPr, where n is the total number of objects taken r at a time.
PAYMENT = 7 letters => 7P5 = 2520
There are 2,520 ways
For butterfly, its quite tricky because there are two letters. Oder does matter here, since no matter which t comes first, that is still the same. So, this is what you do:
BUTTERFLY = 9 letters
9P5 ÷ 2! => since there are two same letters
15120 ÷ 2 = 7560
There are 7560 ways.
