plzz someone help me out with (i)

the best way to solve this is to find probability, p(m') for males who don't watch Kops are Kids then Final answer would be 1 - p(m')

P(m') = 18/30 * 5/18 = 1/6
Now 1 - P(m') = 5/6

can anybody help me out to sketch the first condition on an argand diagram?
only the first condition [ (a - z)/(b-z) = phi/2 ]

P(x) = 2x^3-3x^2+5x-2 . It is given that (2x-1) is a factor of p(x) and that when p(x) is divided by (x-2) the remainder is 12 . Find the quadratic factor of p(x). ANS:x^2 – x + 2

question # 9
thank u so much

np
So it is very simple.
Input d value of domain into d function and respective values will be d value of range.
here wen u put zero in equation u will get -1
and wen u put pi in equation u will get 3
so -1 <= f(x) <= 3 will b d answer
