Justin Bieber has 7 white chips, 5 red chips, and 8 blue chips in a bag. Without looking, he pulls a chip out, records the color, and puts it back in the bag. He does this 200 times. About how many times could Justin expect to pull out a blue-chip

8/20 = 0.4 = 40% of the chips are blue

Step-by-step explanation:

0.4 × 200 = 80

so he probably pulled the blue chip out about 80 times

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
