Answer:
C
Step-by-step explanation:
Normal distribution has a unique characteristic of having equal mean and median values. If mean was higher than median, then the distribution would be positively skewed. Mean lower than median would appear in distributions negatively skewed. Each data set has a median value.
 
        
             
        
        
        
Answer:
a,480 over 60=80cm3
b,(c over 24)the whole cubed=480 over 60
c*60=24*480
c=11520/60
=192
 
        
             
        
        
        
From trigonometry we know that: 
if 
then,  (where
 (where  is an integer)
 is an integer)
This can be rewritten in degrees as:
 .............(Equation 1)
.............(Equation 1)
Now, in our case, 
Therefore, (Equation 1) can be written as:
 ..........(Equation 2)
..........(Equation 2)
Now, to find the correct options all that we have to do is replace n by relevant integers and find the values of  that match.
 that match.
For n=2, (Equation 2) gives us:  .
.
Thus, 
Now, we know that: 
Let n=-1, then:

Thus, 
Likewise, 
Only the last option  will never match
 will never match  because no integral value of
 because no integral value of  will ever give
 will ever give 
Thus the last option is the correct option.
 
        
                    
             
        
        
        
Answer:
Dilation changes (x,y) values not the grid or coordinate plane. Basically, dilating a graph or a coordinate grid means the original coordinates you may have had will be changed with the dilation.  For example, a triangle plotted had its original area of 26 dilated to an area of 58. 
 
        
             
        
        
        
Let the two integers be x and x + 1, then
2(x + 1) + 9 = 3x
2x + 2 + 9 = 3x
3x - 2x = 11
x = 11
Therefore, the integers are 11 and 12.
