What I understand from the picture given, she had 2 ribbons with the length of 1/4. 
These would be the two shortest ones. 
So: 1/4 + 1/4 = 2/4
      = 1/2
I hope this helps and I know that it is different to what HimyBrainy put but it is what I understood! :/ 
        
             
        
        
        
Answer:
q1=11
q3= 33
Step-by-step explanation:
The data set has 44 number of students. The first quartile is 25 %  of the numbers in the data set . So 
25 % of 44 = 25/100 * 44= 0.25 *44 = 11
So the first quartile lies at 11.
Similarly the third quartile lies at the 75 % of the numbers of the data set . So
 75 % of 44 = 75/100 * 44= 0.75 *44 = 33
So the third quartile lies at 33.
 
        
             
        
        
        
Answer:
5
Step-by-step explanation:
We can subtract both sides of the equation by 3, getting 3 + p - 3 = 8 - 3.
Then we can evaluate, getting p = 8 - 3 = 5.
