Formula for the Minimum Sample size 
The least biased estimate for p and q is 1/2. 

Thus 



 
        
             
        
        
        
We have
<span>3/5=(a+5)/25
3/5=(5/5)*(3/5)=15/25
therefore
15/25=</span>(a+5)/25<span>
15=a+5------------------------ > a=10
the answer is the option </span>a = 10
        
                    
             
        
        
        
Answer:
1. 40.00 sq units
2. 37.5 sq units
Step-by-step explanation:
1. Given slant height as 3 and the square base side as 4,
-The surface area of a right squared pyramid is calculated by summing the areas of the 4 triangles and the square base:

Hence, the area of the square pyramid is 40.00 sq units
2. The surface area of a cube is equivalent to 6 times the side of one face.
-Given the dimension of the sides as 2.5, surface area is obtained as:

Hence, the surface area of the cube is 37.5 sq units
 
        
                    
             
        
        
        
Answer:
No solutions.
Step-by-step explanation:
If you normalize the second one by dividing by 2, you get:
y = 5/2x+4.
Now you see that both have the same slope (5/2). They are parallel lines that never intersect.
