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).

Step-by-step explanation:
Let's represent Ben's current age by x and his age in 16 years, x+16.If in 16 years, his age will be 3 times his age now, the equation is x+16=3x
x+16=3x
x-x+16=3x-x
16=2x
16/2=2x/2
8=x
Therefore Ben is 8 years old.
Tan a=3/11
a=arctan(3/11)
a=15.26 degrees
Answer:
164.73
Step-by-step explanation:
1. convert 57% into a decimal by dividing it by 100.
--> 57/100 = 0.57
