1. This answer would be C, n^3 + 5
2. This answer would be D, n^3 + 9
3. This answer would be A, 4n - 11
<span>Yes, the two events are independent because P(NF|PB) = P(NF).
I'm not 100% sure though so wait til someone else answers :)</span>

<u>Trigonometry</u>
- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] tanθ = opposite over adjacent
Step-by-step explanation:
<u>Step 1: Identify</u>
Angle θ = 35°
Opposite Leg BC = <em>x</em>
Adjacent Leg AC = 2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [Tangent]: tan35° = x/2
- Isolate <em>x</em>: 2tan35° = x
- Rewrite: x = 2tan35°
- Evaluate: x = 1.40042
- Round: x ≈ 1.40
