Mean is the average number in the data set.
To get the average we first add all the numbers.
After we add all these numbers we then divide by the number of numbers in the data set.
So we do 22+18+38+6+24+18 which is equal to 126 there are six numbers so we divide 126 by 6. This gives us a mean of 21.
ANOTHER EXAMPLE:
Another example of this is the data set (4,65,7,34,5)
We first add all the numbers and get 115 then we divide by 5 and get 23 as the mean.
3(y+1)+2y=8
3y + 3 +2y = 8
5y +3 = 8
-3 -3
5y = 5

Answer:
Volume of the Figure ![=825.38m^3](https://tex.z-dn.net/?f=%3D825.38m%5E3)
Step-by-step explanation:
Volume of the figure = Volume of the Upper cone+Volume of the lower cone
Volume of a cone = ![\pi *r^2*\frac{h}{3}](https://tex.z-dn.net/?f=%5Cpi%20%2Ar%5E2%2A%5Cfrac%7Bh%7D%7B3%7D)
Volume of the Upper Cone with
![radius=6m](https://tex.z-dn.net/?f=radius%3D6m)
![3.14*6*6*\frac{12}{3}](https://tex.z-dn.net/?f=3.14%2A6%2A6%2A%5Cfrac%7B12%7D%7B3%7D)
![=3.14*6*6*4\\\\=3.14*36*4\\\\=3.14*144\\\\=147.14m^3](https://tex.z-dn.net/?f=%3D3.14%2A6%2A6%2A4%5C%5C%5C%5C%3D3.14%2A36%2A4%5C%5C%5C%5C%3D3.14%2A144%5C%5C%5C%5C%3D147.14m%5E3)
Volume of the Lower cone with
and ![height=18m](https://tex.z-dn.net/?f=height%3D18m)
![=3.14*6*6*\frac{18}{3} \\\\=3.14*6*6*6\\\\=3.14*36*6\\\\=3.14*216\\\\=678.24m^3](https://tex.z-dn.net/?f=%3D3.14%2A6%2A6%2A%5Cfrac%7B18%7D%7B3%7D%20%5C%5C%5C%5C%3D3.14%2A6%2A6%2A6%5C%5C%5C%5C%3D3.14%2A36%2A6%5C%5C%5C%5C%3D3.14%2A216%5C%5C%5C%5C%3D678.24m%5E3)
Volume of the Whole Figure = ![147.14+678.24](https://tex.z-dn.net/?f=147.14%2B678.24)
Volume of the Figure ![=825.38m^3](https://tex.z-dn.net/?f=%3D825.38m%5E3)

Answer:
(x, y) ⇒ (-x, y)
Step-by-step explanation:
When you're looking for a rule that transforms one figure to the other, the first step is to look at the figures. You want to identify their orientation (order of vertices) and the relative locations of corresponding vertices.
Here, vertices VWX are in <em>clockwise</em> order. The corresponding vertices V'W'X' are in <em>counterclockwise</em> order. For that to happen, there must be a reflection involved.
The y-axis goes through the midpoints of VV', WW' and XX'. This means the y-axis is the line of reflection. The coordinates of V'W'X' have the same y-values as their originals, but their x-values have changed sign.
The algebraic rule for these two figures is ...
(x, y) ⇒ (-x, y) . . . . . . reflection over y-axis; sign of x changes
__
<em>Additional comment</em>
No rotation is involved here.
The rule (x, y) ⇒ (x, y+10) means the y-coordinate has had 10 added to it. That causes a translation upward by 10 units. This <em>is</em> the algebraic rule.
