Answer:
C. 47°
Step-by-step explanation:
The angle between the terminal ray of 227° and the nearest x-axis (the negative x-axis) is ...
227° -180° = 47°
The reference angle is 47°.
_____
In mathematical terms the reference angle is the minimum of the angle modulo 180° and the supplement of that angle.
227° modulo 180° = 47°
180° -47° = 133° . . . . supplement of 47°
min(47°, 133°) = 47° . . . the reference angle
#1: The whole value of data is 21.
There are 21 data values on the dot plot.
#2: The number of data values is 14.
#3: The unit is: 21 ÷ 14.
And it is 1.5.
#4: A statistical question can be answered by collecting data and where there will be variability in that data.
