Openen
3. five juniors and four seniors have applied for two open student council positions. school
administrators have decided to pick the two new members randomly. what is the probability
they are both juniors or both seniors?

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

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

: )

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
