There are 91 such ways in whih the volunteers can be assigned if two of them cannot be assigned from 14 volunteers.
Given that a school dance committee has 14 volunteers and each dance requires 3 volunteers at the door, 5 volunteers on the floor and 6 on floaters.
We are required to find the number of ways in which the volunteers can be assigned.
Combinations means finding the ways in which the things can be choosed to make a new thing or to do something else.
n=n!/r!(n-r)!
Number of ways in which the volunteers can be assigned is equal to the following:
Since 2 have not been assigned so left over volunteers are 14-2=12 volunteers.
Number of ways =14
=14!/12!(14-12)!
=14!/12!*2!
=14*13/2*1
=91 ways
Hence there are 91 such ways in whih the volunteers can be assigned if two of them cannot be assigned.

Answer:
8
Step-by-step explanation:
The distance or the length between two points can be computed using the formula:
X₁ = x-coordinate of first point
X₂ = x-coordinate of the second point
Y₁ = y-coordinate of first point
Y₂ = y-coordinate of the second point
When we right down the coordinates of a point, we always start with the X and then the Y.
(X,Y)
You have the following coordinates or points
Point 1: (-3,4)
Point 2: (5,4)
Based on that we have the following given:
X₁ = -3
X₂ = 5
Y₁ = 4
Y₂ = 4
Now we just fill in the formula:
