The price of a gallon of milk at various stores is normally distributes with a mean of $2.89 and a standard deviation of $0.2. The price if a gallon of mil at Ralphs has a z-score of -1.3 while the price of a gallon of milk at Albertsons has a z-score of 0.6. How much more is a gallon of milk at Albertsons compared to Ralphs?

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

answer:

your answer is: c. 196 7/8 in^3.
