There are 20! number of ways for everyone to do this so that at the end of the move, each seat is taken by exactly one person.
People are seated in a 2 by 10 rectangle grid. All 20 persons stand up from their seats and relocate to an orthogonally neighboring one upon the blowing of a whistle.
Now, we have to find the number of possible ways in which each seat is taken up by exactly one person after the move.
As the number of people is 20 and 20 seats are to filled exactly once.
So, the number of ways = 20!

Answer: 2
Have a good day ¯\_(ツ)_/¯
Answer:
First box: 2
Second box: 30
Third box: 42
Step-by-step explanation:
5 sixes means 5 · 6, which equals 30. An unknown amount of sixes equals 12, which is 2 because 2 · 6 = 12.
30 + 12 = 42
7 · 6 = 42, so 42 is the answer.

Answer:
This means that the correct initial value problem for the population p(t) as a function of time is is 
Step-by-step explanation:
The population of a town increases at a rate proportional to its population:
This means that this situation is modeled by the following differential equation:

In which k is the growth rate.
By separation of variables, the solution is given by:

In which P(0) is the initial population.
Initial population of 1000.
This means that the correct initial value problem for the population p(t) as a function of time is is 
Answer:
d = (R+3)(M)
Step-by-step explanation:
d/M - 3 = R
Add 3 both sides
d/M = R+3
Multiply M both sides
d = (R+3)(M)
