A flute instructor examined student progress.he found that playing a longer song does not necessarily mean that a student will h
ave more or fewer wrong notes.what can he conclude?

Answer:
The flute instructor can conclude that the length of the song does not have a direct variation or correlation with the number of incorrect notes.
Step-by-step explanation:
Direct variation and correlation means that as the "x" variable increases, the "y" variable will change according to it.
If the flute instructor took numerical data, for example, made a chart, and graphed it, then he would not find a trend.
It would probably look like this (see first photo). The plotted points are all over the place. ("x" is the song length, "y" is the number of incorrect notes).
If there was a correlation, then the data would look more like a straight line (see second photo).

Approximately .
Step-by-step explanation:
Convert the angle of this sector to radians:
.
The formula relates the arc length
of a sector of angle
(in radians) to the radius
of this sector.
In this question, it is given that the arc length of this sector is . It was found that
radians. Rearrange the equation
to find the radius
of this sector:
.
