5. Evan is picking marbles out of a bag. The results are recorded below. Red 24 Blue 16 Yellow 10 Green 22 8 Black What is the experimental probability of picking a black marble? Write answer as a percent.

10%

Step-by-step explanation:

24 R + 16 Blu + 10 Y + 22 G + 8 Bla = 80 total

Then you cant set up a proportion:

In order for 80 to become 100, you must multiply it by 1.25. That means in order to get X, the probability of pulling a black marble, you can multiple 8 x 1.25

8 x 1.25 = 10

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
