How do you find the variance of a set of numbers?
1. Find the arithmetic mean (average)2. Find the distance of each number from the mean (x-the mean=?)3. Square each number4. Add up all of the squares5. Divide the final sum by the original meanEX: Set: 1, 3, 4, 5, 71. 1 + 3 + 4 + 5 + 7 = 20 / 5 = 42. 1-4=-3 3-4=-1 4-4=0 5-4=17-4=33. 3*3=9 1*1=1 0*0=0 1*1=13*3=94. 9 + 1 + 0 + 1 + 9 = 205. 20 / 4 = 5
What is the slope of (-7-8) and (0 4)?
If you mean points of: (0, 1) and (4, 4) Then the slope is: 3/4
What is the slope of 01 and 44?
If you mean points of: (0, 1) and (4, 4) Then the slope is: 3/4
What is the sum of squared deviations for 2 2 0 5 1 4 1 3 0 0 1 4 4 0 1 4 3 4 2 1 0?
2,2,0,5,1,4,1,3,0,0,1,4,4,0,1,4,3,4,2,1,0

What is the mean of 0 1 2 3 4?
The arithmetic mean is 2.
What is the slope of the passing line points (0 4) and (-8 -1)?
If you mean points of: (5, 4) and (0, 3) then the slope is 1/5

What is the variance of these four scores 0 1 1 2?
Variance = sigma((value - mean)2) / (# values - 1) Mean = (0+1+1+2)/4 = 1 Variance = ((0-1)2+(1-1)2+(1-1)2+(2-1)2)/(4-1) Variance = (1+0+0+1)/3 Variance = 2/3 Variance ~ 0.667
How you to divide 8 liter in to 4 liter in 5 liter and 3 liter?
each row has the contents of 8 5 3 in that order 8 0 0 5 0 3 5 3 0 2 3 3 2 5 1 7 0 1 7 1 0 4 1 3 4 4 0 the other solution is 8 0 0 3 5 0 3 2 3 6 2 0 6 0 2 1 5 2 1 4 3 4 4 0 See related link "Dividing" for more info
