Answer:
2.16
Step-by-step explanation:
The question is on mean absolute deviation
The general formula ,
Mean deviation = sum║x-μ║/N where  x is the each individual value, μ is the mean and N is number of values
<u>Team 1</u>
Finding the mean ;

Points     Absolute Deviation from mean
51                          2
47                         2
35                        14
48                         1
64                         15
<u>Sum    </u>                 34           
Absolute mean deviation = 34/5= 6.8
<u>Team 2</u>
Finding the mean

Points                      Absolute deviation from the mean
27                                    15.8
55                                    12.2
53                                     10.2
38                                      4.8
41                                       1.8
<u>Sum                                 44.8        </u>
Absolute deviation from the mean = 44.8/5 =8.96
Solution 
Difference in mean absolute deviation of the two teams = 8.96-6.8 = 2.16
 
        
             
        
        
        
Answer:
w = -7z/2
Step-by-step explanation:
We need to solve for w in terms of z.
The equation given is:
5w + 9z = 2z + 3w
Collect like terms:
5w - 3w = 2z - 9z
2w = -7z
w = -7z/2
 
        
                    
             
        
        
        
Harry can rake the leaves in the yard 8 hours faster than his little brother Jimmy can. 
<span>If they join to work together they can complete the job in 3 hours. </span>
<span>1/x + 1/(x - 8) = 1/3 </span>
<span>3(x - 8) + 3x = x(x - 8) </span>
<span>x^2 - 14x + 24 = 0 </span>
<span>(x - 12)(x - 2) = 0 </span>
<span>Solutions: </span>
<span>x = 2 </span>
<span>x = 12 </span>
<span>Jimmy can complete the job on his own in 12 hours.</span>
        
             
        
        
        
Suppose f(x) is an even function. The range of g(x) = -3f(2x) is [-9, 3].
Suppose f(x) is an odd function. What is the range of 0.5f(x-3) is [-1.5, 0.5]
