Which of the following sets of four numbers has the largest possible standard deviation? (1, 2, 5, 6) (4, 5, 5, 6) (1, 3, 5, 7) (6, 7, 8, 9)

< 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

the correct answer is x/3+10≥32

hope this !

table 3 represents a direct variation function. : )
