No it is not a function because the 2 repeats and for it to be a function none of the x values can repeat.

The domains are -8, 0, 2, 2, 7 (when it asks for domain it is asking for the x values)

The ranges are 7, 1, -6, 3, 9 (when it asks for range it is asking for the y values)

Answer:

C(x)=24,000+19,200x

Step-by-step explanation:

<u>Mathematical Modeling</u>

To model a real-life situation, a mathematical model can be constructed in such a way it accurately represents the variables measured in the system.

This problem requires to build a model for the yearly cost of a small and successful business.

The first data is the fixed monthly cost or the money the owner must pay regardless of the number of employees he hires. This cost includes shipping supplies and products for $2,000. To operate for a full year, the fixed cost is 12*$2,000=$24,000.

The other component of the cost function is the variable cost of x employees. Given each employee costs $1,600 each month, having x employees cost 1,600x each month. For a full year, the variable cost will be

12*1,600x=19,200x.

We finally form the total cost function:

\boxed{C(x)=24,000+19,200x}

Inclusion-exclusion formula for 3 events. write aubuc = (aub)uc and use the inclusion-exclusion formula three times to derive th
nadya68 [22]

solution:

We are going to use this property: P(A U B) = P(A) + P(B) – P(AB)  

First we treat (A U B) as one event as follows:

P( (A U B) U C) = P( A U B ) + P(C) – P((A U B)C)

  = P( A U B ) + P(C) – P(AC U BC)

                            = P(A) + P(B) – P(AB) + P(C) – P(C) – P(AC U BC )

                             =P(A) + P(B) – P(AB) + P(C) –P(AC) – P(BC) + P(ABC)

                             = P(A) + P(B) + P(C) – P(AB) – P(AC) – (BC) + P(ABC)
