Answer:
Correct me if i am wrong but i believe it is 126
Step-by-step explanation:
Angle BOC = 252 (angles around a point = 360 so 360-108 =252)
x=126 (The ange at the centre of a circle is twice the size the angle at the circumference. 252 is at the centre and x is at the circumference so 252/2 = 126)
Answer:
Step-by-step explanation:
The mean absolute deviation of the following set of data is 4.5
Step-by-step explanation:
We need to find the mean absolute deviation of the following set of data.
10,20,12,4,18,8,14,18
For finding mean absolute deviation, first we need to find the mean of the given data set.
The formula used to calculate mean is:
Sum of all data points: 10+20+12+4+18+8+14+18 = 104
Number of data points = 8
So, mean is:
Now, we will subtract 13 from the given data points:
10 - 13 = -3
20 - 13 = 7
12 - 13 = -1
4 - 13 = -9
18 -13 = 5
8 - 13 = -5
14 - 13 = 1
18 - 13 = 5
We will take absolute values i.e |-a|=a
So, now the numbers will be:
3,7,1,9,5,5,1,5
We will now find absolute mean deviation by finding mean of newly calculate values
Sum of all data points = 3+7+1+9+5+5+1+5
Number of data points = 8
So, the mean absolute deviation of the following set of data is 4.5
28 is 43.75% of 64
you can calculate this by making a fraction of 28/64 and timing this by 100!
