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
Answer:
Sum of 3 angles in a triangle=180
x+55+72= 180
x+ 127=180
x= 180-127
x= 53
Answer:
1.2 x 10⁴
Step-by-step explanation:
12,000 has 2 places of other numbers before a spam of zeroes.
Take the numbers before zeroes and put a decimal to the left of the last digit.
Last digit is 2 so a decimal goes before 2
1.2
Count how many places the decimal moved: this number is your power of 10.
12000. --> 1.2000
It moved 4 places.
12,000 = 1.2 x 10⁴
