Question

please give me this answer​

Answer 1

7. 15.75

Ans. 15.40+18.00+16.50+14.75+12.60+17.25

= 94.50/6

= 15.75

8. 34

first we put all numbers in ascending orders like

0, 8, 18, 25, 31, 34, 39, 46, 53, 65, 72

there are 11 numbers. our middle is the 6th no. so

the median value of this set of numbers is 34

9. 23

as in given set 23 occurs most often (4 times) so 23 is the modal marks.

10. 12

arrange the set in ascending order

8, 9, 10, 12, 13, 15, 17

in this set middle no. is 12

11. 10.4

mean = 7+9+10+11+15/5

= 52/5

= 10.4

12. 20

in the given set 20 is most common value occuring 4 times so mode is 20

13. 5.6

first five prime nos. are 2, 3, 5, 7 and 11

so mean = 2+3+5+7+11/5

= 28/5

= 5.6

14. 12

12 is the most middle value of the given set after arranging it in ascending order.
