step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

i got 10.28 but that rounds up to 10.3

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
