What is the third quartile of this data set? 20, 21, 24, 25, 28, 29, 35, 37, 39, 42, 44
A. 24
B. 44
C. 29
O D. 39
SU

D

Step-by-step explanation:

First find the median of the data set

The median is the middle value of the data in ascending order

20,  21,  24,  25,  28,  29,  35,  37,  39,  42,  44

                                      ↑ median = 29

The third quartile is the middle value of the data to the right of the median

35,  37,  39,  42,  44

               ↑ third quartile

The third quartile of the data set is 39

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
