Here is a list of numbers: 5, 3, 10, 11, 12, 9, 7 ,20 ,4 State the median.

9

Step-by-step explanation:

List them in order first.

3, 4, 5, 7, 9, 10, 11, 12, 20

Now find the middle number:

3, 4, 5, 7, 9, 10, 11, 12, 20

   4, 5, 7, 9, 10, 11, 12

       5, 7, 9, 10, 11

           7, 9, 10,

               9

Median = 9

Step-by-step explanation:

Arranging it in ascending order:

=> 3, 4, 5, 7, 9, 10, 11, 12, 20

Median is the middlemost no. so

=> Median = 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
