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,

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:
Step-by-step explanation:
<u>The gray triangles have</u>
- Base of 20 cm and added height of 60 cm for 2 triangles in each section of AMND and MNCB
<u>The grey area in total is</u>
- 1/2*20*60 + 1/2*20*60 = 20*60 = 1200 cm²
-3.
Multiply 60 with 4 and then find the factor when added together which would give you the middle number. Notice that because it is a negative equation that both signs are negative. This means that the biggest factor of 240 will be negative.
Then, rewrite the equation 4x^2 +12x -20x -60 and divide it into two parts (4x^2 + 12x) (-20x-60) and then factor each part. If done correctly, the numbers left in the parenthesis should be the same. This way the part outside is one factor and the part inside is the other. This should get you 4x -20 and x +3.
Set both equal to zero and you get your two solutions. One is -3 and the other is 5.
Hope this helps!
