In the next election, 15,000 people will actually vote for Candidate A. A poll has a percent error of 4%. Which statement descri
salantis [7]

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.

error = 15000 \times \dfrac {4}{100}

error = 600

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 />V = 15000 +/- error

V = 15000 + 600 = 15600

or

V = 15000-600 = 14400

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.

By factoring, identify the zeros of the quadratic function f (x) = x²-9x-22
vovikov84 [41]

Answer:

x= -2, x= +11

Step-by-step explanation:

I hope this is right!

To factorise, we need two numbers that add to make -9 and multiply together to make -22.

2 - 11 works, so we put it in the brackets in this order.

(x + 2) (x - 11)

so x + 2 = 0 and x - 11 =0

but we could also simplify this to say that x could be either -2 or + 11.

I hope this helps.

Have a lovely day.

Find the slope of the line that passes through (-6, -2) and (-7, -2)
Jobisdone [24]

Answer:

0

Step-by-step explanation:

We could use the Slope Formula to find the answer, but there's an easier way of doing it. Notice that the y-coordinates of both points are the same. This means that the line that passes through these points is horizontal, which makes our answer 0 because all horizontal lines have a slope of 0.

All horizontal lines have a slope of 0 because the value of y never changes as the value of x changes, so if we were to input any two points on a horizontal line into the Slope Formula, our numerator would be 0 (because anything subtracted from itself is 0), leaving us with a result of 0 regardless of the denominator since 0 divided by anything is 0. Hope this helps!
