if a number cube is rolled, how many times would we expect to get a number less than four out of 200 trials?

25
50
75
100
question 2
if we expect to get a number less than 3 in eighty times spinning an eight-part spinner numbered 1 to 8, how many times would we have spun?

60
120
240
320
question 3
jessica has three assists in nine soccer games so far this season. based on her results so far, how many assists would we expect her to have if there are thirty-three games in the season?

7
10
11
27

Im like 100% percent sure its 27 for question number 2

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

cosine
