About Nevaeh314
Ask me about: Social Situations, Relationships, Depression, Suicide, Health, How to Deal with Loss, School, Random weird things that don't fit into any of the above ;) I think I'm pretty good at giving advice, just ask and I'll give it my best shot. I've experienced a lot of it, and I don't mind doing a little research if I haven't. I love playing piano, clarinet, in general I just love music, and I love to write and read, poetry especially, and I love mathematics, physics, and oceanography. I've been told I'm mature for my age, but I don't know, I just think that a person has to be who they are, true to themselves, and not worry about what fits into an age group. I love simply living as best as I can, working when I have to, and having fun. It's all in your perspective. Just a quote that I like "Dreams are made and broken, potentials realized and never reached, all on the breath of one phrase: It could be."

..since you're good at math, would you mind helping me?
it looks like a simple question, but I keep getting i wrong, here's the question;
In a class with 12 boys and 18 girls, the average height for boys was 180 cm, and for the girls it was 165 cm. What is the class' average?
:S The answer is supposed to be 171 cm.
But I don't know how to get there, and WHY, I keep getting the wrong answer.
Please help?
Wow, lol. I feel stupid, I'm in calc and it still took me about 5 minutes to figure this one out.
If you want the average of the whole class, you don't want the average of the average of the girls and boys, which would be 180+165/2=172.5
What you want to do is take 180 x 12 (to get the heights of all the boys added together) plus 165 x 18 (to get the heights of the girls, then added to the heights of the boys) then divide by the total number of people in the class (30).
You should get 171.
Hope this helps! :)

Haha yeaah thank you!! ♥ that's what I did at first, the whole 180+165/2 and I thought there was something wrong with my calculations since it was so close to 171, but not really. Haha that explains it..thank you, babe ♥
