Determine the difference between the mean and standard deviation of: 33, 44, 43, 56, 55, and 30.

mean = ( 33+44+43+56+55+30) / 6

= 261/6

= 43.5

variance = 96.92

standard deviation = √96.92

= 9.84

difference between mean and standard deviation

= 43.5 - 9.84

= 33.66

could you reply to this with the question so i can ?

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
