Answer:
Step-by-step explanation:
The correct answer is B). X
Step-by-step explanation:
Every function got a set of input values called " Domain " and a set of respective output values as " Range"
And function worked as Function( Input value ) = Output value
There are basic rules for function :
1. There always exist output value for every single input value.
2. Every input value should have one and only one output value
<em>For W :</em>
Rule 2 is violated
Here, Input value 6 result to two output value 2 and 4
<em>For X :</em>
No rule is violated
<em>For Y :</em>
Rule 2 is violated
Here, Input value 6 result to two output value 2 and 6
<em>For Z :</em>
Rule 2 is violated
Here, Input value 7 result to two output value 2 and 8
<em>The correct answer is B). X </em>
Answer:
z(max) = 650 $
x₁ = 10 units
x₂ = 15 units
Step-by-step explanation:
That is a linear programming problem, we will use a simplex method to solve it
Formulation:
Let´s call x₁ number of chairs and x₂ number of tables then :
Item (in hours) cutting assembly finishing Profit ($)
Chairs (x₁) 1 2 1 20
Tables (x₂) 2 1 1 30
Availability 40 42 25
Objective Function
z = 20*x₁ + 30x₂ ( to maximize) subject to:
x₁ + 2x₂ ≤ 40
2x₁ + x₂ ≤ 42
x₁ + x₂ ≤ 25
x₁ , x₂ >= 0
Using excel or any other software we find:
z(max) = 650
x₁ = 10
x₂ = 15
I assumed that 3 households are sampled.
Now, is the number in each of these households equal to 1, 3 and 8 people?
Next, the question says, samples of n=2 are randomly selected (with replacement) from these 3.
So are sample space is
11
13
31
33
18
81
38
88
83
88
This is done 9 times.
Is that how you understand the problem?
When they select the household with only 1 person, the variance is 0
When they select the household with 8 people, they variance will be from a discrete uniform distribution
Similarly for household with 3 individuals.
