Answer:
Below in bold.
Step-by-step explanation:
Minimum 24
Lower quartile 29
Median  43
Upper quartile = (49 + 51) / 2 =  50
Maximum = 56
Interquartile range =  50-29 = 21.

Hello.
The mathematical concept of this problem is basic once you get down to it. The question asks, "How many 
times more minutes does Shawn listen to than Greg?"
Remember the "How many" rules:
· "How many more" suggests 
subtraction· "How many times" suggests 
divisionLet's also take a look at our opening sentence: "For every 9 minutes of music Shawn listens to, Greg listens to 4 minutes of music." This means we can set it up as a fraction, as we have the phrase "For every" in our sentence. So, let's do that.

 is our fraction;
To simplify, we need to divide our numerator (the number on the top) by our denominator (the number on the bottom).
9 / 4 = 2.5
This is our rate, or how many 
times more music Shawn listens to than Greg.
Your answer is: "Shawn listens to 2.5 times more music than Greg."
I hope this helps!
 
        
        
        
This would be a rise over run solution, which means the answer would be -1400/8000, when simplified this equals -40/7, a.
