A store has a box of coupons at the entrance. There are 600 20% coupons; 250 30% coupons; and 150 50% coupons. Each customer entering the store gets to pick a coupon from the box. Let n represent the percent value of the discount coupon. a. Find the probability that a customer picks a 30% discount coupon. Enter as a decimal rounded to TWO places. b. What is E(n )

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°
