Answer:
21.186%
Step-by-step explanation:
z = (x-μ)/σ, 
where 
x is the raw score = 2400mg
 μ is the population mean = 2000mg
σ is the population standard deviation = 500mg
z = 2400 - 2000/500
z =	0.8
Probability value from Z-Table:
P(x<2400) = 0.78814
P(x>2400) = 1 - P(x<2400) = 0.21186
Converting to percentage:
0.21186 × 100
= 21.186%
Therefore, the percent of the meals 
 ordered that exceeded the recommended daily allowance of 2400 mg of sodium is 21.186%
 
        
             
        
        
        
Step-by-step explanation:
all angles of a triangle sum to 180
180 = 15x + 24x +21x
 180=60x
solve for x
then substitute that for 24(x) to get the angle
 
        
                    
             
        
        
        
Two !!!! ...  unless this is some riddle and there's a huge in depth meaningful answer i'm unaware about o.O
        
             
        
        
        
The distance formula is:  d  =  sqrt( (x2 - x1)2 + (y2 - y1)2 )
 
For this problem, let (-5, -4) be the "first" point, so  x1 = -5  and  y2 = -4
                      and let (-6, 4) be the "second" point, so  x2 = -6  and  y2 = 4.
 
Then:  d  =  sqrt( (-6 - -5)2 + (4 - -4)2 )  =  sqrt( (-1)2 + (8)2 )  =  sqrt( 1 + 64 )  =  sqrt( 65)
 
The distance formula is just the Pythagorean Theorem applied to an x-y graph.
 
You would get the same final answer if you let (-5, -4) be the second point and (-6, 4) be the first point.
