<span>Answer: option B. She did not set the width of the compass to the radius of the circle.
Explanation:
1) If she sets the compass to an arbitrary width to </span><span>draw the arc to cut the circle, the point obtained will not be to the right distance from the first vertex.
2) All the adjacent vertices on a regular polygon have the same distance one from each other.
3) In the hexagon that distance is the same radius, which you can see becasue you can form six equilateral triangles inside the circle, whose side lengths are the radius.
4) So, she should set the width of the compass to the radius of the circle.

The probability that a randomly selected pigeon gets an incorrect result is; 0.0103
<h3>How to find the Probability?</h3>
We are told that;
1.5% pigeons are infected.
Inaccuracy of the test = 1 - 97% = 3%
1.5% of the pigeons are infected. Thus;
1 - 1.5% = 98.5% pigeons are un-infected.
Inaccuracy of test is 1 - 99% = 1% .
Thus;
0.03 and 0.01 are the probability of an error being made in infected and un-infected respectively.
Meanwhile, probability of infected and un-infected are 0.015 and 0.985 respectively.
Thus, the probability of a randomly chosen person gets an incorrect result = (0.03*0.015) + (0.985*0.01) = 0.0103

Answer:
x intercepts: (-1,0) and (2.5,0)
It will be a minimum because the coeficcent for the degree is positive. The coordinates of the vertex are: (.75,-6.125)
To graph this I would first draw points on the vertex (.75,-6.125) and the x intercepts (-1,0) and (2.5,0). I would then simply just sketch a parabola that met all those points.
