Answer:

469 is your answer....

Answer 2

Answer:

Mean - 17

Median - 18

Mode - 20

Step-by-step explanation:

Finding mode -

10,13,14,15,15,18,20,20,20,21,21

20 is the most repeated number- 3 times- and thus the mode.

Median -

11+1/2 = 12/2 = 6th term = "18"

Mean -

10+13+14+15+15+18+20+20+20+21+21/ 11

= 187/11 = 17
