Make a box-and-whisker plot of the data. 60,63,53,66,65,58,51,55,58,51,58,62 ,53,66,61,51,65,52,54,50

Step-by-step explanation:

To do this by hand, first sort data (you can use wolfram to do this).

Then divide data into four parts.

50, 51, 51, 51, 52, 53, 53, 54, 55, 58, 58, 58, 60, 61, 62, 63, 65, 65, 66, 66

Q1 = (52+53)/2 = 52.5

Q3 = (62+63)/2 =  62.5

IQR = 62.5 - 52.5 = 10

x >  Q3 + 1.5*IQR  or  x < Q1 - 1.5*IQR

=> There are no outliers.

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
