Standard deviation is simply the square root of the variance.
We need to get the square root of each variance to see whether its standard deviation is greater than its variance.
A. 0.25 ⇒ √0.25 = 0.50B. 1.75 ⇒ √1.75 = 1.32C. 2.5 ⇒ √2.5 = 1.58D. 1.5 ⇒ √1.5 = 1.22
Among the choices, only A. 0.25 has a standard deviation that is greater than the variance. The standard deviation is 0.50
Answer:
Step-by-step explanation:
Using slope and one point method, the equation of a line become
y-y1= m(x-x1)
y+3= -3(x+1)
y+3= -3x-3
y= -3x -6
The set-up 25/100= 50/? is incorrect.
The correct set-up should be ?/50= 25/100.
?= 50* (25/100)= 12.5.
The correct answer is 12.5~
Answer:
<em>See the graph attached</em>
x-intercept(s), y-intercept, vertex, and axis of symmetry for the function shown
- x-intercepts = (- 3, 0) and (- 1, 0)
- y-intercept = (0, 3)
- vertex = (- 2, - 1)
- axis of symmetry is the line x = - 2
