How many ways can 4 people stand in line for movie tickets?

24 ways people can stand in a line

Step-by-step explanation: In this problem we're asked how many ways can 4 people stand in a line for movie tickets.

Let's start by drawing 5=4 blanks to represent the 4 different positions in the line.

Now, we know that 4 different people can fill the spot in the first position. However, once the first position is filled, only 3 people can fill the second spot and once the second spot is filled, only 2 people can fill the third spot and so on.

Now based on the counting principal, we will multiply these numbers together to find out how many ways these 4 people can stand in a line.

Therefore, there are 24 ways 4 people can stand in a line for movie tickets.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
