Answer:
2.16
Step-by-step explanation:
The question is on mean absolute deviation
The general formula ,
Mean deviation = sum║x-μ║/N where x is the each individual value, μ is the mean and N is number of values
<u>Team 1</u>
Finding the mean ;
![mean= \frac{51+47+35+48+64}{5} =49](https://tex.z-dn.net/?f=mean%3D%20%5Cfrac%7B51%2B47%2B35%2B48%2B64%7D%7B5%7D%20%20%3D49)
Points Absolute Deviation from mean
51 2
47 2
35 14
48 1
64 15
<u>Sum </u> 34
Absolute mean deviation = 34/5= 6.8
<u>Team 2</u>
Finding the mean
![mean=\frac{27+55+53+38+41}{5} = 42.8](https://tex.z-dn.net/?f=mean%3D%5Cfrac%7B27%2B55%2B53%2B38%2B41%7D%7B5%7D%20%3D%2042.8)
Points Absolute deviation from the mean
27 15.8
55 12.2
53 10.2
38 4.8
41 1.8
<u>Sum 44.8 </u>
Absolute deviation from the mean = 44.8/5 =8.96
Solution
Difference in mean absolute deviation of the two teams = 8.96-6.8 = 2.16
Answer:
x<100
Step-by-step explanation:
The given equation is :
x-19<81
Adding 19 to both sides of the equation.
x-19+19<81+19
x<100
It means the solution of the given equation is less than 100. Hence, the attached figure shows the graph for the given equation.
