In statistics, the standard deviation (SD, also represented by the Greek letter sigma σ or the Latin letter s) is a measure that is used to quantify the amount of variation or dispersion of a set of data values.
Answer:
B. 2, -0.5
Step-by-step explanation:
Given the equation

Rewrite it as

Graph the graph of the quadratic function 
The grapg of this function is a parabola going downwards.
This parabola intersects the x-axis at points x = -0.5 and x = 2, so the solutions of the equation are x = -0.5 and x = 2
18%==59.04
20%=65.60. $124.65 +$÷328.=$452.64 $452.64
total $124.65
-3 is the y intercept, so place a point there. The slope is 3/4. So from your -3 point, go up 3 and over 4. Make a point. Do that another time and also from the -3 intercept go down 3 and over left 4, the. you’ve got yourself a nice line.
