Answer:
Step-by-step explanation:
As per midsegment theorem of a trapezoid,
Segment joining the midpoints of the legs of the of the trapezoid is parallel to the bases and measure half of their sum.
Length of midsegment = 
3). MN = 
            = 14
4). MN = 
            = 66.5
5). MN = 
     7 = 
     14 = AB + 10
     AB = 14 - 10
     AB = 4
6). 15 = ![\frac{1}{2}[(3x+2)+(2x-2)]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5B%283x%2B2%29%2B%282x-2%29%5D)
     30 = 5x 
      x = 6

Answer: Null hypothesis : 
Alternative hypothesis : 
Step-by-step explanation:
Let  be the proportion of women using supplements and
 be the proportion of women using supplements and  be the proportion of women who did not to have died during that period .
 be the proportion of women who did not to have died during that period .
Then the set of hypothesis for testing if the proportion of women elderly women who use dietary supplements is different than those who do not will be :-
Null hypothesis :  [∵ it takes equality sign]
     [∵ it takes equality sign]
Alternative hypothesis :  [∵ it takes ≠ sign to show difference]
    [∵ it takes ≠ sign to show difference]
 
        
             
        
        
        
If you are asking to solve for x the answer is:
x = 2
