Question

Consider a tree diagram representing all the possible final outcomes of this scenario: You buy a computer with 5 choices of color, 9 choices of monitor size, 12 choices of hard-drive size, and either a regular or a large battery. How many "leaves" does the tree have?

Answer 1

i got 1080 but needto show work!

Answer 2

# of combos = (# of colors)*(# of monitor types)*(# of hdd types)*(# of battery types)

Answer 3

so you're just multiplying out all the different numbers given

Answer 4

but 5*9*12 isnt 1080?

Answer 5

you're forgetting the battery type counts

Answer 6

regular or a large battery

so you have to add in a *2 in there

Answer 7

5*9*12*2 instead of just 5*9*12

Answer 8

okay see i wouldve never guessed to multiply the 2

Answer 9

you are a life saver! :P

Answer 10

yw

yeah i fell for that trap too because i just multiplied out all of the visible numbers without actually reading it first

Answer 11

yeah. i think we all do (:

Answer 12

which is why a lot of text books will say "two books" instead of "2 books" so students won't just pick out the visible numbers

Answer 13

yeah common since.

Answer 14

definitely, wish they wouldn't throw in those traps though lol

Answer 15

i know , like they want us to fail? lol

Answer 16

lol who knows, maybe it's just trying to see if you're paying attention and not falling asleep

Answer 17

Answer 18

lol I know I do sometimes when I'm reading a boring textbook

Answer 19

Ironically, that happens when I'm reading a section that says "...to date, there are no known cures for insomnia..." lol jk

Answer 20

what is the slope of a line that goes through the points(2,5) and (8,6)?

Answer 21

use the slope formula


m = (y2-y1)/(x2-x1)


m = (6-5)/(8-2)


m = ??
