​

Answer 1

5) X= 10,15,20,25,30      f=6,8,p,10,6

fixi = 60,120,20p,250,180

∑fixi= 610+20p

∑fi = 30+p

mean = 20.2

20.2=610+20p/30+p

606+20.2p=610+20p

20.2p-20p =610-606

0.2p = 4

p= 20

Answer 2

$<b>$ Heyaaa mate

Here is your answer

x = 10,15,20,25,30

f = 6,8,p,10,6

fixi = 60,1 20,20p,2 50,180

fixi = 610 + 20p

fi = 30+p

mean = 20.2

20.2 = 610 + 20p /30+p

606+20.2p= 610+20p

20.2p-20p = 610-606

0.2p= 4

p = 20

Hope it helps you
