Answer:
C
Step-by-step explanation:
5(4) over 6(4) makes more sense than the others do
In the spreadsheet, you get 1 for the mean and 0 for the MAD.
The mean of the dog washing time is 17, and the MAD is 5.5.
To find the mean, add all of the data points together and divide by 9, the number of data points:
15+20+10+18+25+10+12+30+13 = 153/9 = 17
To find the MAD, first find the difference between each data point and the mean; take the absolute value; then average these together.
|15-17|=2
|20-17|=3
|10-17|=7
|18-17|=1
|25-17|=8
|10-17|=7
|12-17|=5
|30-17|=13
|13-17|=4
2+3+7+1+8+7+5+13+4=50/9=5.5
The correct answer should be nine
Answer:
29 years
Step-by-step explanation:
11 x 27 = 297 = total of all the ages of the women
9 x 32 = 288 = total of all the ages of the men
297 + 288 = 585 = total of all the ages of everyone
585/20 = 29.25 ≈ 29

Hey there!
The solution of -14.5<x, shows that x is greater than and not equal to -14.5.
The third graph from the top shows this.
Hope this helps :)
