Often, variability is most usefully expressed in the same units as the original data. That's what <em>standard deviation</em> (square root of variance) does. In situations where that is the case, the variance is useful only for getting to the value of standard deviation.
Where is the rest of the question?
Answer:
2/5
Step-by-step explanation:
y=2/5x-6
m=2/5
y=mx+b
Slope: 2/5
y-intercept: 6
Answer:
360 ft.
Step-by-step explanation:
Each base distance is 90 so since there are 4 bases you solve:
90*4 = 360
Answer:
The coefficient is 1
Step-by-step explanation:
There is an imaginary 1 in front of variables that becomes the coefficient if there isn't already a number there. If it was 5x squared, the coefficient would be 5.
