D.

Answer 1

this is chart

Answer 2

I'm confused, your original problem states that you spun it 51 times, yet your chart does not equal 51.

Answer 3

hmm

Answer 4

no 50 times

Answer 5

can u solve it

Answer 6

So how was the data from the table supposedly obtained? It doesn't make sense unless it adds up to how many time it's spun originally.

Answer 7

hmm this is the original

Answer 8

Oh, I understand, one moment, I just need to work this out real quick.

Answer 9

Ok, so have you tried adding up the # of spins from the data table? If not, do so and tell me the total.

Answer 10

100

Answer 11

right

Answer 12

Exactly, so you could logically say then that however many times the spinner landed on each color is essentially already it's percentage likelihood. For instance, red was landed on 17 times out of 100. Therefore it's got a 17% chance of being landed on next time. Understand?

Answer 13

ok

Answer 14

Ok, so knowing that white has a likelihood of 49% (or about half), you need to take that percentage and multiply it by the number of spins you are going to do.

Answer 15

49*100=49000

Answer 16

right

Answer 17

No no no, percentages are converted into decimals by moving the decimal TWO places to the LEFT. so, for instance, 15% = .15, and 142%=1.42. Get it?

Answer 18

oh so 0.49

Answer 19

Yep, now multiply that by 50.

Answer 20

24.5

Answer 21

Which is rounded up to which of your answers?

Answer 22

25

Answer 23

right

Answer 24

Yep! That's your answer.
