20, मापनो `x_(1),x_(2),x_(3),...........x_(20)` का औसत y, है। तब, `(x_(1)-101),(x_(2)-101),(x_(3)-101)...... (x_(20)-101)` का औसत ज्ञात करे?

Consider the observation x_(1)=1, x_(2), x_(3)=3, .............x_(100)=100 x_(101), x_(102), x_(103), x_(104)=104 Median of the given data is

If average of 20 observation x_(1), x_(2), ……x_(20) is y . then the average of x_(1) - 101, x_(2) - 101, x_(3) - 101, ……. X_(20) - 101 is :

Consider any set of observations x_(1),x_(2),x_(3),..,x_(101) . It is given that x_(1) lt x_(2) lt x_(3) lt .. Lt x_(100) lt x_(101) , then the mean deviation of this set of observations about a point k is minimum when k equals

Consider any set of observations x_(1),x_(2),x_(3),..,x_(101) . It is given that x_(1) lt x_(2) lt x_(3) lt .. Lt x_(100) lt x_(101) , then the mean deviation of this set of observations about a point k is minimum when k equals

Consider any set of observations x_(1),x_(2),x_(3),..,x_(101) . It is given that x_(1) lt x_(2) lt x_(3) lt .. lt x_(100) lt x_(101) , then the mean deviation of this set of observations about a point k is minimum when k equals

Write down the value of int_(-101)^(101) x ^(101) dx.

If f(x)=prod_(n=1)^(100)(x-n)^(n(101-n)); then (f(101))/(f'(101))=
