Question

The polynomial x3-kox2+9x has three real zeros if and only if, k satisfies (1)kl 56 (2) k=0 (3) |k|>6 (4)lk26​

Answer 1

Answer:

Answer

Mean =sum of observation/ no. of observations

=2+3+4+5+0+1+3+3+4+3/10

=28/10

=2.8

mean = 2.8

median

let us write given observatins in ascending order

= 0123333445

here no. of observations r 10 which is an even no.

therefore observation at 5th and 6th place is at middle position ile. 3 and 3

median = sum of observation at 5th and 6th place / 2

= 3+3/2

=6/2

=3

median = 3

mode= observation which repeated maximum time

= 3

mode = 3
