Answer:
<em>C. Omitted variable bias
</em>
Step-by-step explanation:
In mathematics and statistics, omitted-variable bias (OVB) happens if one or more important variables is left out by a statistical model.
The bias results in the equation being related to the expected effects of the included variables by the influence of the excluded variables.
Answer:
Remember that the slope of perpendicular lines are negative reciprocals of each other.
Step-by-step explanation:
y = 1 - 2x the slope is -2 the value of the x term.
So the slope of the new line using point (- 1, 2) is 1/2.
Now use y = mx + b where y = -1, x = 2, and m = 1/2 .
y = mx + b
-1 = 1/2(2) + b solve for "b", the y-intersect
-1 = 1 + b
-2 = b
The line that is perpendicular to y = 1 - 2x is y = 1/2x - 2
