A bag contains 4 red, 2 blue, 6 green, and 8 white marbles. What is the probability of selecting a white marble at random from this bag, not replacing the marble, and then selecting another white marble? Round your answer to the nearest tenth of a percent if necessary.

14.7

Step-by-step explanation:

So first you add all the marbles together, which equals 20.

-you the put 8 over 20= 8/20

Next you subtract one from the eight and add it all together again= 7/19

The equation should look like

-(7/19)·(8/20)

This would equal .147

simplified to 14.7

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
