Answer:
19.5 (Rounded: 20)
Step-by-step explanation:
In math, the mean is every number added together, then divided by the amount of numbers. For example, 1,2,5,4,8 would have a median of 4.
<em>(1 + 2 + 4 + 5 + 8 = 20 ÷ 5 = 4)</em>
Your dot plot has 14 total numbers, meaning that you add up all the numbers and divide by 14.
16 + 17 + 17 + 17 + 17 + 19 + 19 + 19 + 19 + 21 + 22 + 22 + 23 + 25 = 273
273 ÷ 14 = 19.5
If you don't need to round, 19.5 is correct. However, if you need to round my best guess is 20. Good luck!

Step-by-step explanation:
We know 10 1/2 is basically 10.5 or 21/2
To find the max amount of scarves she can make, simply divide the number of yards she has by 4. This will get you the number of scarves she can create.
Well.. we don't want to make .625 of a scarf since that would be ridiculous, so we will round it down to 2 since we can't make 3 either.
The max amount of scarves she can make is 2.
The answer to your question is c)15
Total=110=D+J+K
D=(2/3)J
K=2J
...a...
If J=x,
D=(2/3)x ⟨— i
K=2x ⟨— ii
...b...
T=D+J+K
110=(2/3)x+x+2x ⟨— b
...c...
110=2x/3+3x/3+6x/3
110=11x/3
330=11x
330/11=x
30=x
D=(2/3)x
D=(2/3)(30)
D=20
