Answer:
66.4 in^2
Step-by-step explanation:
Surface area is defined as the area around the surface of a 3-dimensional solid. The shape we are given here is a triangular prism with a square base. This means it contains one square and 4 triangles on the surface. To find the surface area, we just need to find the areas of all 5 surface shapes and add them up. We have been given that the square has a side length of 4 inches, meaning the area is 4^2 or 16. The area of a triangle is (1/2)base*height. The base length is 4 inches and the height is 6.3, and (1/2)*4*6.3 is 12.6. Note that, since there are four triangles, we have to multiply this value by 4 (12.6*4 = 50.4). Now we have the area of the square and the area of all the triangles put together, so we can just add them up:
16 + 50.4 = 66.4
Answer:
22 rounds down to 20 if that is what you are asking
Step-by-step explanation:
You did not finish your question i dont think. 22 DOES round down to 20 though.

1. 
2. 
3. 
Step-by-step explanation:
Given information:
(1)
We need to find the value of P(s₁|I).
Therefore the value of P(s₁|I) is 
.
(2)
We need to find the value of P(s₂|I).
Therefore the value of P(s₂|I) is 
.
(3)
We need to find the value of P(s₃|I).
Therefore the value of P(s₃|I) is 
.
