A box contains 100 colored chips; some are pink and some are blue. Milton chooses a chip at random, records the color, and places it back in the bag. Milton has recorded 12 pink chips and 18 blue chips. Using these results, what is the predicted number of pink chips in the box? 30
40
82
88

40

12:18 is a 2:3 ratio of pink to blue

If this ratio continues for the population of the box;

the ratio has 5 parts. 100/5 = 20. Each part is 20.

2 * 20 = 40

3* 20 = 60

P:B = 40:60

40 pink chips and 60 blue chips

hope it helps!

 B) 40

Explanation:

12 pink, 18 blue, 12+18 = 30 total

12/30 = 0.40 = 40% of the chips Milton recorded are pink

So, of the 100 chips in the box, we expect 0.40*100 = 40 chips to be pink.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
