Answer:
690 sq in
Step-by-step explanation:
SA = LA + 2B where LA is the lateral area and B is the area of the base
The triangular base has an area of
B = 1/2bh 1/2(5)(12) = 30
LA = ph where p is the perimeter of the base and h is the height of the prism
LA = (12 + 5 + 13)(21) = 30(21) = 630
SA = 630 + 2(30) = 630 + 60 = 690 sq in

![CV=\frac{0.1317}{1.72}=0.07657](https://tex.z-dn.net/?f=CV%3D%5Cfrac%7B0.1317%7D%7B1.72%7D%3D0.07657)
The relative variability is almost equal in both samples a slight greater variability can be noticed in the first sample.
Step-by-step explanation:
The coefficient of variation of a sample is defined as the ratio between the mean standard deviation and the sample mean. And it represents the percentage relation of the variation of the data with respect to the average.
![CV=\frac{S}{\bar X}](https://tex.z-dn.net/?f=CV%3D%5Cfrac%7BS%7D%7B%5Cbar%20X%7D)
In the case of the first sample you have:
![CV=\frac{0.1252}{1.57}=0.07975](https://tex.z-dn.net/?f=CV%3D%5Cfrac%7B0.1252%7D%7B1.57%7D%3D0.07975)
In the case of the second sample you have:
![CV=\frac{0.1317}{1.72}=0.07657](https://tex.z-dn.net/?f=CV%3D%5Cfrac%7B0.1317%7D%7B1.72%7D%3D0.07657)
The relative variability is almost equal in both samples a slight greater variability can be noticed in the first sample.
Divide them both by 6
So it should be : 3/4
Answer: 1) The missing length is 40. 2) The missing side is 30 .
Step-by-step explanation:
1) 9^2 + b^2 = 41^2
81 + b^2 = 1681
-81 -81
b^2 = 1600
b= 40
2) 24^2 + 18^2 = c^2
576 + 324 = c^2
900 =c^2
c= 30
