QUESTIONE The time taken in minutes to complete a 5 kilometre race by a group of 10 runners is given below: 18 ,21 ,16, 24, 28, 20 ,22 ,29 ,19,23 1.1 Calculate the mean time taken to complete the race.

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 y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

50-60=10
