Hello there,
You want to split them into gender specific groups.
So...
Find the HCF(highest common factor) of 60 & 72
The answer will be shown in the picture
I have done 2 methods :))
Answer:
5z+30
Step-by-step explanation:
5(z+6)
^ multiply each term in the parentheses by 5
5z+5x6
then,
5z+5x6 (multiply the numbers)
the answer will be 5z+30
B is the answer but check if u can simplify it
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 ;
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
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
9/10 is bigger. 10/10 is a whole so in decimal 9/10 is .90
