Answer: 
B :it is the ratio of the area of the circle to the area of the square from a cross section.
Step-by-step explanation:
had this question on ed2020 and got it right^
 
        
                    
             
        
        
        
Calculate for the mean/ average of the given numbers:
 
                             μ = (1 + 2 + 3 + 4 + 5) / 5 = 3
Then, we calculate for the summation of the squares of differences of these numbers from the mean, S
 
                             S  = (1 - 3)² + (2 - 3)² + (3 - 3)² + (4 - 3)² + (5 - 3)²
                                S = 10
Divide this summation by the number of items and take the square root of the result to get the standard deviation.
                              SD = sqrt (10 / 5) = sqrt 2  
                                    SD = 1.41
Thus, the standard deviation of the given is equal to 1.41. 
              
                            
        
                    
             
        
        
        
Answer:
3/4
Step-by-step explanation:
You can do this two different ways. Both include picking two points where the line crosses a corner. I'm using (0,-1) and (4,2). Now here you can either use
Slope=
or  
  
If you use the first one start at point (0,-1) and go to point (4,2) and count how many it goes up (rise) and then put that over how many it goes to the right (run).
If you use the second one then plug in the numbers.
y2=second y point
y1=first y point
x2=second x point
x1=first x point
 Now just solve.
   Now just solve.
