the world cup ( I think) happens every 3 years or 4 years?
Every century means every 100 years
An event that occurs once every three years.
I assume you mean every four years and yes it is held every four years
The word Biennial means Every two years
Every 2 years
Oh, dude, you mean besides my existential crisis? Ha, just kidding. The Olympics happen every 4 years, so I guess you're looking for something that happens more often. How about the World Choir Games? They happen every 2-3 years, so there you go, a fun fact for your next trivia night.
I think they take place every 3 years..... I'm not sure, srry
every 3 months
every 3 years
Annually mean every year.
3 years
The mean is the average. To get an average age of three, 3 of her pets would have to 4 years old and the other 3 would be 2 years old. In ten years she would have 3 pets that are 14 and three that are 12, therefore the mean age of them would be= [(14*3)+ (12*3)]/6= 13 So in following the same concept, 20 years the mean age of her pets would be 23.
