Abag contains 45 marbles of various colors. jon draws 60 times, each time replacing the marble before drawing again. he gets a total of 12 blue marbles. which is best prediction of how many blue marbles are in the bag? a. 5 b. 9 c. 12 d. 15

d. all of the above

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
