The answer is X=27 degrees
Steps-
90-63=27
8, 11, 12, 13, 16, 42
Add together and divide by 6 to get the mean.
102/6 = 17
Find the middle of the data for the median.
(12 + 13)/2 = 12.5
The mean is 17, the median is 12.5, and the mean is more affected by the outlier. 17 (the mean) is not a good measure of center.
I believe it is 2c^8, but I'm not sure.
Answer:
The first pyramid:
63x
39x 24x
23x 16x 8x
The second pyramid:
162x
82x 80x
4x 78x 2x
The third pyramid:
12a+2b
9a+b 3a+b
9a b 3a
The fourth pyramid:
-19a
-5a -14a
3a -8a -6a
Step-by-step explanation:
All that an alegbra pyramid is is adding the two terms below it.
So you can see how I added the terms that lied below each number, such as in number 1: I added 23x and 16x to get me 39x, and I added 16x and 8x to get me 24.
Hope this helped!
