Answer:
x=y
Step-by-step explanation:
let x be the number of tennis balls and y the number of rackets.
-We divide the number of balls by the number of rackets to find out their ratio of proportionality:
-Hence, for each one ball there is one racket, so;
-This relationship is linear in nature, a direct variation, and can be graphed as attached below:
Y=Mx+B -> slope intercept form
The answer would be -3y=-5x-9
Divide the -3 on both sides and you get
y=5/3x+3
We start by ordering the values.
5, 7, 8, 10, 13, 14, 17, 17, 21
Now we find the median(middle number).
Median(b): 13
(I added (b) for "base" since we need to take more medians)
The median now divides this data into two halves.
Now we take the medians of the two remaining halves.
Median(Half1): 7.5
Median(Half2): 17
Mark off the minimum and maximum.
Min: 5
Max: 21
Now graph!
Your median(Half1) is incorrect, since your median for the first half is 9. Since our median for the first half is 7.5, the answer would be Answer Choice C.
The first board is approximately 0.45 the second board is approximately 0.9 and the third board is approximately 19.8
