There are no choices but the association is :
Very strong negative linear association
Answer:

Step-by-step explanation:
From the question we are told that:
Waiting time for a container of the wheels during production 
Average processing time is 
Wheel per container 
Total wheel per day 
Policy variable of
Generally the equation for Total number of container
is mathematically given by

Where
Total time 

Therefore





Therefore the number of Kanban containers needed for the wheels is

You answer is 3 and here's why...
7x + 5 - 3x - 7 = 10
First you must collect like terms
And that gives us
4x - 2 = 10
Next you must simplify by removing additives
4x - 2 + 2 = 10 + 2
4x = 12
Now you must divide
4x/4 = 12/4
x = 3
Answer:
2 sqrt(2x-1)
Step-by-step explanation:
f(x) = sqrt( x+9)
g(x) = 8x-13
f(g(x))
place the function g(x) in for x in f(x)
f(g(x)) = sqrt(8x-13+9)
Combine like terms
f(g(x)) = sqrt(8x-4)
Factor out 4
f(g(x)) = sqrt(4*(2x-1)
2 sqrt(2x-1)
