Abag contains 5 blue marbles, 6 red marbles, and 9 green marbles. two marbles are drawn at random, one at a time and without replacement. what is the probability of selecting two blue marbles? a. 9/20 b. 3/38 c. 1/19 d. 11/20

The answers is C) 1/9

3+x

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
