Suppose a jar contains 5 red marbles and 36 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same time, find the probability that both are red.

5%

Step-by-step explanation:

Because 36 is bigger than 5 . So the Blue marbles can be on the top, middle, bottom and the Red marbles are hiding

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.

i suppose it should be (y=2x-5)
