Enable to get the median. you have to put the numbers in order from least to greatest. Once you have done that, if there are two numbers in the middle, add them up and divide by 2. 
your IQR is: 14.75 
&& your Median is: 21.5 
I believe. I hope this is right 
        
             
        
        
        
16/99 
8/9
2/9
do the last three have a decimal in the start?
        
             
        
        
        
1.) The interval of the value of x is from -5 to 1, inclusive. Remember that what is asked is the absolute value, thus the sign does not matter even if you have to subtract x from 5. Thus, the maximum value would be obtained if the x is smaller, which is 1. The minimum value is obtained when x=-5.
Absolute maximum value: 
x = - 5f(-5) = ║5 - 7(-5)^2║ = ║-170║=
170Absolute minimum value: 
x = 1f(1) = ║5 - 7(1)^2║ = ║-2║= 
2
2.) The Mean Value Theorem (MVT) applies to functions that are continuous and differentiable on the closed and open interval of a to b, respectively. Since the function is a quadratic function, MVT can be applied. Then, this means that there is a value of c which is between a and b. This could be determined using this formula according to MVT:

The differentiated form would be f'(x) = -2x. Then,


Thus, x = -1, x = -1/2, and x=0 all lie in the function 4-x^2.
