Answer:
A.
Step-by-step explanation:
B doesn't make sense because the honors class is only a group of very few people, so that isn't a reasonable survey.
C. is unfair because only 5 boys is just as unfair as B, maybe is more.
D. There isn't a 100% chance the teachers would know EXACTLY what their students would want and there opinions. The chance of all of the teachers knowing what choice their student would make is very slim.
A. is correct because it gives most of the students a chance to state their opinion on what they want to see on Broadway. A fifth isn't much, but those lucky students will get to cast there vote and opinion fairly.
Hope this helps!

Answer:
I'm pretty sure its C or D I could be wrong still but.
For this case we must follow the steps below:
step 1:
We place each of the given points on a coordinate axis
Step 2:
We join the AC points (represented by the orange line)
We join the BD points (represented by the blue line)
It is observed that the resulting figure after placing the 4 points on a coordinate axis, turns out to be a rhombus.
In addition, the blue and orange lines turn out to be perpendicular, that is, they have an angle of 90 degrees between them. This can be verified by finding the slopes of each of the two straight lines (blue and orange), which must be opposite reciprocal, that is, they comply:
In this case, the slope of the orange line is and that of the blue line is
Then , it is verified that they are perpendicular.
Thus, the conclusion is that ABCD is a rhombus and AC is perpendicular to BD.

Option D
Yes, they are.
But this does not happen if a was a vector.
