22) Using the Cook's distance statistic Di to determine influential points in a multiple regression model with k independent variable and n observations and letting Fv1,v2 denote the critical value of an F distribution with v1 and v2 degrees of freedom at a 0.50 level of significance, Xi is an influential point if 22) A) Di < Fn-k-1,k 1 B) Di < Fk 1,n-k-1 C) Di > Fk 1,n-k-1 D) Di > Fn-k-1,k 1

i dont know and i dont care for math bc it is a stupied subject

step-by-step explanation:

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°

hope this

the answer is d on edge
