The standard deviation of the numbers 14 22 6 9 11 23 15 18 20 12 is 5.67646 the mean is 15 and the standard deviation variance is 32.222.
I’m not sure if i understand…
Hey there!
Here is your answer:
<u><em>The proper answer to this question is "true".</em></u>
<u><em>Since how the number pi (3.14..... or π) goes on forever and cannot be turned into a simple fraction its irrational.</em></u>
<em>Therefore the statement:</em><span><em>The number pi goes on forever with no repeating pattern; therefore it is irrational is true!</em></span><em />
If you need anymore help feel free to ask me!
Hope this helps!

Answer:
160 square units
Step-by-step explanation:
8^2 = 64
1/2 * 6 * 8 = 24
4 sides * 24 = 96
96 + 64 = 160
Area of the base = 24^2 = 576 cm^2
Now find the slant height of each side :-
by pythagoras
s^2 = 12^2 + 16^2 = 144 + 256 = 400
s = sqrt 400 = 20 cm
so the area of the 4 triangular sides = 4 * 1/2* 20 * 24 = 960 cm^2
total surface area = 576 + 960 = 1536 cm^2
