Plz victoria used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 times. the results are shown in the tables below:

color of marble number of times rolled
blue 18
green 20
yellow 12

heads tails
20 30

using victoria's simulation, what is the probability of pulling a blue marble and the coin landing tails up?

the probability of getting tails up is 30/50 or most likely

the probability of getting a blue marble is 18/5 or least likely

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

0.02
