Answer:
Average Mean = 1.8
Step-by-step explanation:
Missing:
X:0 1 2 3 4 5 6
P(x): 0.20 0.30 0.20 0.15 0.10 0.05
Computation:
Average Mean [Probability distribution]
∑[P(x) × X]
= 0 x 0.20 + 1 x 0.30 + 2 x 0.20 + 3 x 0.15 + 4 x 0.10 + 5 x 0.05
= 1.8
Average Mean = 1.8

Answer:
yearly salary = $54,708
Step-by-step explanation:
Let monthly salary be x
Let yearly salary be y
Let number of months be n
To estimate your average monthly salary, divide your yearly salary by the number of months in a year. This can be written as
x = y divided by n
Therefore, writing an equation to determine yearly salary is the same as making the yearly salary 'y' the subject of the formula above:
where y = ???
x = $4,559
n = 12 months
Therefore yearly salary = $54,708

- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] cosθ = adjacent over hypotenuse
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Angle θ = 34°
Adjacent Leg = <em>x</em>
Hypotenuse = 4.8
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [Cosine]: cos34° = x/4.8
- Isolate <em>x</em>: 4.8cos34° = x
- Rewrite: x = 4.8cos34°
- Evaluate: x = 3.97938
- Round: x ≈ 4
