I believe a qualitative prediction requires a prediction with out any numerical data to support it while a quantitative predictions require a prediction supported by numerical data.
A real world example of this is in chemistry during a lab.  qualitative data is based off of observation with out numerical data such as a color change.  quantitative data is based off of observation with numerical data such as the mass changes.
(quantitative prediction is decision from data based on percentages, probabilities, and so on while qualitative predictions are based off of given information).
I hope this helps and let me know if you need further explaining.
        
             
        
        
        
Hey there! 
The correct choice is D. 5(2 + y)
As you can see, the expression matches the description 
5 times = 5( The parentheses directly next to the 5 means to multiply what is inside the parentheses by that number, in this case, 5
The sum of 2 and y = (2 + y)
Therefore, that makes D the CORRECT option 
Hope this helps you!
God bless ❤️

Answer:
She started with 50 stamps
Step-by-step explanation:
Hi! For these types of problems we always result to going backwards. So, she now has 30 right? So, to reverse into the problem, we do the opposite of what it says. "She then bought five more" 30 - 5 = 25. Then it says she sold half of them. 25 x 2 = 50. If we recheck by going back, she sold half of them (50 / 2 = 25) and she bought five more (25 + 5 = 30).
Hope this helps!
