Answer:

a. The Venn diagram is explained in the attached word file.

0.61                                    

b. Not independent

Step-by-step explanation:

a. The hypothetical 1000 table for given situation is

                                          Adult(A)        Not Adult (not A)        Total

Travel outside (T)                 610                170                               780

Not Travel outside (not T) 110                110                               220

Total                                 720                280                               1000

P(Adult and travel outside)=P(A and T)=610/1000=0.61

b. Multiplication rule for independent events is

P(A and B)=P(A)*P(B)

P(A and T)=0.61

P(A)*P(T)=0.72*0.78=0.56

As P(A and T) is not equal to P(A)*P(T), so event "being an adult" and "travel outside" are not independent.

photoshop1234 [79]

Answer:

C(p) = p*50 + 300

Step-by-step explanation:

Using the names:

Clm: cost of labor and materials

Crm: fixed cost on rent and equipment

p: number of phones

and Ct: total cost

the ecuation would be number of phones times the cost and material plus the fixed cost, something like this

p * Clm + Crm = Ct

on the example we have all the data except the rent and equipment cost (the fixed cost) so thats what we need to solve

producing 3 phones its

3 *¨50 + Crm = 450

Crm = 450 - 150 = 300

so replacing in the above formula the equation would be

C(p)=p * 50 + 300
