The answer to your question is x = -0.171

Step-by-step explanation:

Equation

                         3 - 5 = 13

Process

1.- Pass -5 to the right side

                         3 = 13 + 5

2.- Simplify

                        3  = 18          

3.- Get logarithm in both sides of the equation

                  (8x + 4)log 3 = log 18

4.- Pass log 3 to the right side

                  8x + 4 = log 18 / log 3

5.- Solve for x

                  8x = log 18/log 3 - 4

                    x = 1/8 [log 18 / log 3 - 4]

6.- Use the calculator to find x

                    x = 1/8 [ 1.255/0.477 - 4]

                    x = 1/8 [ 2.631 - 4]

                    x = 1/8 [ -1.369]

                   x = -0.171

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
