Answer: 12
Step-by-step explanation:
If we have n people and we want to do groups of 4, the total number of different combinations is:
and we want find the smallest n such c > 365.
let's do it by brute force:
if n = 5, we have:
if n = 6
if n = 7
if n = 8
if n = 9
if n = 10
So you can see the patern here.
So we have the previous number multiplied by n and divided by n - 4
if n = 11
C = 210*11/(11- 4) = 330
if n = 12
C = 330*12/(12 - 4) = 495
Then the minimum number of members such we have more than 365 combinations is 12 members
Answer:
There are about 1609 meters in 1 mile. ... in 1 mile
x+y+z=180
Since y+z=5x, x+5x=180, so x=30
So,
30+y+z=180
y+z=150
Since z=y+24, y+y+24=150
2y=126
y=63
30+63+z=180
z=87
So x=30, y=63, z=87
