1.) To find the surface area, we want to find the area of each side, then add them all up together:
Area of base=lwA=(5)(5)A=25 cm²
Area of triangle=1/2bhA=(1/2)(5)(12.5)A=31.25 cm²
Since the 4 triangles have the same area, we can multiply the area we found by 4 and then add the area of the square:
SA=(4)(31.25) + 25SA=125+25SA=150 cm²
2.) <span>To find the volume use the formula: 
V=(1/3)lwh
V=(1/3)(5)(5)(12.5)
V=104.167 cm^3</span>
        
             
        
        
        
8.525 is rounded to 8.53 because the 5 rounds up so the 2 turns into a 3
        
             
        
        
        
Answer: false
The sample is a randomly selected representation of the population, therefore it cannot represent the true data with 100% accuracy. 
As the sample size increases, the sample proportion approaches the population proportion.
        
                    
             
        
        
        
Answer:
 =AC or 7.8102=AC
=AC or 7.8102=AC
Step-by-step explanation:
If we connect a line from point A to point C we create a triangle, and we can use pythagorean theorem to find this distance. So the line from point A to point C will be our hypotenuse and the other two distances will be out side lengths. 

25+36=
61=
 =AC or 7.8102=AC
=AC or 7.8102=AC
 
        
             
        
        
        
If m(slope)=3, you can start to set up the equation as y=3x+b.
Using y=3x+8, you can plug in the given point being (8,5).
y=5
x=8
5=(3*8)+b
5=24+b
b=-19
The equation would be y=3x-19
