Which quadratic function best fits this data?
1 answer:
The data has a peak at x=5, so we expect it to be modeled with a parabola that opens downward. That is the x² coefficient will be negative.
For x=1, the third choice gives a better approximation to (x, y) = (1, 32) than does the first choice. It is appropriate to choose
... y = -11.41x²+154.42x-143.9
_____
The quadratic regression function of a graphing calculator confirms this choice.

Complete the above statements
Considering the third statement in the question;
First, it should be noted that a circle is a full sector that measures 360 degrees
Assuming the circle is divided by a central angle of 180, the number of sectors formed will be;
Further assume the circle is divided by a central angle of 90, the number of sectors formed will be;
Similarly, if the circle is divided by a central angle of n, the number of sectors formed will be;
Hence, from the list of given options; fills the gap correctly
