<h3>
Answer: Approximately 2.33</h3>
The variance is given to be 5.43
Apply the square root to the variance to get the standard deviation
s = standard deviation
v = variance
s = sqrt(v)
s = sqrt(5.43)
s = 2.330326 which is approximate
s = 2.33
I rounded to 2 decimal places as this is the number of decimal places used for the variance.
Answer:
{x,y,z} = {1,-1,-2}
Step-by-step explanation:
In this equation you can eliminate the x value
multiply the second equation by -2 and you get:
-2x - 2y = -10
when you add the two equations the x factors will cancel
2x + 3y = 6
- 2x - 2y = -10
---------------------
y = 16
you can find the x value by plugging the y value that you now know into one of the equations that you started off with.
Answer:
The absolute value of -10 is -10
Step-by-step explanation:
Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative.
...
Absolute Value (For example)
|6| = 6 means the absolute value of 6 is 6.
