Let u1, u2, · · · , un be independent uniform random variables over [0, ? ] with the probability density function (p. d.f) f(x) = 1 ? , x ? [0, ? ], ? > 0. let u(1), u(2), · · · , u(n) be the order statistics. also let x = u(1)/u(n) and y = u(n) . (a) (5pts) find the joint probability density function of (x, y ). (b) (5pts) from part (a), show that x and y are independent variables

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°
