Answer:
This is a response bias
Step-by-step explanation:
Response bias is a general term for a wide range of tendencies for participants to respond inaccurately or falsely to questions. These biases are prevalent in research involving participant self-report, such as structured interviews or surveys. Response biases can have a large impact on the validity of questionnaires or surveys.
This is exactly what happens here in the excercise, the result of the poll do not match the vote count, both results do not match, therefore, we can see that a lot of people lied in the poll or simply did not answer it very well.
H-5 = -30
Add 5 to both sides to get variable h by itself
h = -25
Any vector that is a multiple of (3, 1) will be orthogonal. These include
.. A (-6, -2)
.. D (3, 1)
_____
The dot-product of these with (-1, 3) is zero:
(-6*-1 +-2*3) = 6 -6 = 0
(3*-1 +1*3) = -3 +3 = 0
You can make a vector orthogonal to a 2-D vector by swapping the coordinates and negating one of them. When you swap the elements of (-1, 3) you get (3, -1). It is usually convenient to negate the one that is already negative, so that would give you (3, 1) as the orthogonal vector.
If you reduce these fractions into simplest form 5/20 is 1/4 because the numerator and denominator can be divided by 5. 9/12 reduced is 3/4 because the numerator an denominator can be divided by 3.
A line segment connecting two points on the circle and going through the center is called a diameter of the circle. Assume that (x,y) are the coordinates of a point on the circle shown. The equation of a circle with center (h,k) and radius r units is (x−h)2+(y−k)2=r2 .
