Answer 2

Step-by-step explanation:

•avg height= total height /total no. of students

65=1300/x

x=1300/65

x=20

so, there are 20 students in the class

•avg height = height total members / no. of members

150=153+150+151+152+x/5

150×5=606+x

750-606=x

x=44 cm

so, height of fifth member is 44cm

•avg of 4 even number from 6-13=

6+8+10+12/4

=36/4=9

avg of 4 odd numbers from 6-13=

7+9+11+13/4

=40/4=10

so, avg of odd numbers from 6-13 is more than that of even numbers

•avg score of sam = total score of Sam /number of matches

=98+25+105+62+65/5

=355/5=71

so, avg score of Sam =71
