In how many ways can the first 4 guest arrive at a party if 15 guest have been invited

The first 4 guests can arrive at party in 1365 ways if 15 guest have been invited

Step-by-step explanation:

Total number of guests invited = 15

We are supposed to find in how many ways can the first 4 guest arrive at a party if 15 guest have been invited

We will use combination

Formula :

Substitute n = 15 and r = 4

So,Total no. of ways =

Hence the first 4 guests can arrive at party in 1365 ways if 15 guest have been invited

Step-by-step explanation:

The first 4 guests can arrive in 32,760 ways.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
