A1 = (1, -2 , 0) ; a2 = (0,1,2) ; a3 = (5,-6,8) ; b = (2,-1,6)
2*a1 = (2, -4,0)
3*a2 = (0, 3, 6)
-------------------
sum = (2, -1, 6) = b
Hope this helps
There isn’t one..........
Answer:
The median is 6
Step-by-step explanation:
Place all numbers in order from least to greatest:
2,3,5,5,6,6,6,6,7,7,7,9
Start by counting off the numbers evenly on each side:
5,5,6,6,6,6,7,7,
6,6,6,6,
6,6
If you are left with 2 numbers after evenly counting off numbers, then right what is in between the two numbers:
6
The formula for the standard error is this:
σM = σ / √N
where
σM is the standard error
σ is the standard deviation
N is the number of samples
So,
σM = 0.45 / √50
σM = 0.0636 or 6.36%
The standard error is 0.0636
