The median of a number set is always the middle number.
In this sequence, the middle number is 5.
Your median is 5!!
Answer:
z (max) = 34500 $
x₁ = 2
x₂ = 3
Step-by-step explanation:
Hilltop College
3 hours per week preparing lessons and grading papers
Serra College
4 hours per week preparing lessons and grading papers
Total hours to spend per week preparing lessons 18
Let´s call x₁ numbers of class at Hilltop College
and x₂ numbers of class at Serra College then:
Objective function
z = 6000*x₁ + 7500*x₂
Constraints:
1.- x₁ + x₂ ≤ 5 the total number of class
2.- 3*x₁ + 4*x₂ ≤ 18
3. General constraints x₁ ≥ 0 x₂ ≥ 0 integers
After 6 iteration optimal solution is: From on-line solver
z (max) = 34500 $
x₁ = 2
x₂ = 3
I think it’s 12.56...... but it’ll work it out
7(2x+5)=4x-9-x
14x+35=3x-9
11x = -44
x = -4
7(2*-4+5)=4*-4-9--4
7(-3)=-21
-21=-21. so it checks out and x = -4
