Will you add the 4 numbers in the chart. I think that sum will be needed.

OpenStudy (yinshy):

its B because if you add them all up you get 100 but they are doing half you get half of the nubers so all your doing is spliting it in half

Directrix (directrix):

Let me see. So, the sum of the numbers in the chart is 100

Directrix (directrix):

The experimental probability of blue is 24/100.

Directrix (directrix):

The spinner is spun 50 more times for a total of 150 spins.

OpenStudy (yinshy):

so C?

Directrix (directrix):

24/100 = x/150 6/25 = x/150

OpenStudy (yinshy):

i got D

Directrix (directrix):

25x = 6* 150 x =

Directrix (directrix):

You have chosen B, C, and D. Which one are you sticking with?

OpenStudy (yinshy):

C

Directrix (directrix):

Do you think the question is asking how many times the spinner will stop on blue during the next 50 spins OR in the total 150 spins? I am wondering.

Directrix (directrix):

Why C?

OpenStudy (yinshy):

hmmm no B

OpenStudy (yinshy):

50 more times so its asking the number of times it will land on blue and 50 is half of 100 so it would be half of overy number on the chart and 24/2 is 12

OpenStudy (yinshy):

*every

Directrix (directrix):

If the question is how many times the spinner will stop on blue during the NEXT 50 spins, then the answer is 12. Because: 24/100 = (24 + x)/150 where x is the number of blue spins in the extra 50 spins. 24*1.5 = 24 +x 36 = 24 + x 12 = x

OpenStudy (yinshy):

right?

Directrix (directrix):

>>50 more times so its asking the number of times it will land on blue and 50 is half of 100 so it would be half of overy number on the chart and 24/2 is 12 I agree.
