  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] sinθ = opposite over hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

Angle θ = 64°

Opposite Leg = <em>x</em>

Hypotenuse = 11

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute in variables [sine]:                                                                           \displaystyle sin(64^\circ) = \frac{x}{11}
  2. [Multiplication Property of Equality] Multiply 11 on both sides:                      \displaystyle 11sin(64^\circ) = x
  3. Rewrite:                                                                                                             \displaystyle x = 11sin(64^\circ)
  4. Evaluate:                                                                                                           \displaystyle x = 9.88673
  5. Round:                                                                                                               \displaystyle x \approx 9.9

Step-by-step explanation:

1. 4^3 = 4 x 4 x 4 = 16 x 4 = 64

2. 64 - 4 = 60

3. 60 ÷ 2 = 30

4. 30 ⋅ 5 = 150

Fill in the blank. A​ _______ probability of an event is a probability obtained with knowledge that some other event has already
motikmotik

Answer:

A​ conditional probability of an event is a probability obtained with knowledge that some other event has already occurred.

Step-by-step explanation:

Conditional probability of an event (A) is a probability obtained with knowledge that some other event (B) has already occurred and is denoted as P(A|B).

It satisfies the following equation:

  • P(A|B)=P(A and B) / P(B)

where P(A and B) is the probability of A and B occurring together.

Conditional probability is applied in many areas of Bayesian statistics and machine learning.
