Answer:
x=4
Step-by-step explanation:
13x+7=8x+27
5x+7=27
5x=20
x=4
The side length of the square base is 18 inches and the height of the pyramid is 9 inches.
Step-by-step explanation:
Step 1:
The volume of a square pyramid is calculated by multiplying the square of the base edge with the height of the pyramid and 
.
The volume of a square pyramid, 
Step 2:
From the given diagram, the base edge is the length of the four base edges which is x inches in this pyramid. a = x inches.
The height of the pyramid is from the base to the top, h = 
inches .
The volume of a square pyramid, 
Substituting the known values, we get
![x^{3} = 6(972) = 5,832. x = \sqrt[3]{5,832} = 18.](https://tex.z-dn.net/?f=x%5E%7B3%7D%20%3D%206%28972%29%20%3D%205%2C832.%20x%20%3D%20%5Csqrt%5B3%5D%7B5%2C832%7D%20%3D%2018.)
So x is 18 inches long.
The side length 
inches.
The height of the pyramid 
inches.
It’s +3 and then multiply 3 each time. I can’t really explain it, but here’s an example
1, 4, 10, 19
1 + 3 = 4,
3x2=6
4 + 6 = 10
etc etc
Class 1 has more variability because both the range and interquartile range are greater than class 2, meaning the data is more spread out.
<h3>What is range and interquartile range?</h3>
The range is the difference between the largest number and the smallest number in a dataset. The interquartile range is the difference between the first quartile and the third quartile of a dataset.
Range and interquartile range are used to measure the spread of a dataset. The higher range and interquartile range is, the greater the spread and variability of the dataset.
