The number of dots tells us how many times we need to add the actual number underneath the dots. So you need to use both.
<h3>
Which number should you use for the mean?</h3>
Let's suppose we have the next set:
{2, 2, 2, 4, 5, 5, 6}
If you graphed it in a dot plot, then you will have:
- 3 dots above the number 2.
- 1 dot above the number 4.
- 2 dots above the number 5.
- 1 dot above the number 6.
A total of 7 dots.
To find the mean, we just compute:
So the number of dots tells us how many times we need to add the actual number underneath the dots. In conclusion, to find the mean you need to use both, the number of dots and the number underneath.

Hello from MrBillDoesMath!
Answer:
x = 4
x = ( -7 + sqrt(29)) /2
x = ( -7 - sqrt(29)) /2
Discussion:
x^3+3x^2-23x-20 factors as (x - 4) (x^2 + 7 x + 5) so x =4 is one root
The roots of the quadratic factor, x^2 + 7x + 5, can be found using the quadratic formula where a = 1, b = 7, and c = 5
x = ( -b +\- sqrt(b^2-4ac)) / 2a
x = ( -7 +\- sqrt( 7^2 - 4*1*5) ) / (2*1) =>
x = ( -7 +\- sqrt (49-20) ) / 2 =>
The "+" root: ( -7 + sqrt(29)) /2
The "-" root: ( -7 - sqrt(29)) /2

<span> line passes through the points (p, a) and (p, –a)
where p and a are real numbers and p ≠ 0
(p, a) and (p, –a) m = Cannot divide by ZERO, there is no slope to this Line.
slope of the line: no slope (does not exist)
equation of the line: x = p Perpendicular Line
</span><span>slope of a line perpendicular to the given line: would be m = 0, horizontal Line y= 3
</span>y- intercept: none
Not sure but I believe letter B) 3+4 is rational since the answer is 7 and 7 is a rational number and it can be expressed as a quotient. The sum of a rational number and an irrational number is irrational. The sum of two rational numbers is rational
Answer:
-3.5 < -3 1/4
Step-by-step explanation:
Since both are negative numbers in this case, we need to find the number closest to zero. But first we need to make sure both the numbers are in the same format. One is in decimal while the other is in fraction form.
-3.5 is also -3 1/2 or -3 2/4
-3 1/4 is also -3.25
seeing how -3 1/4 is closer to zero by .25, that makes it the greater number compared to -3.5
