Amanda has a jar full of marbles. The probability of randomly selecting a blue marble is 1/18 , a red marble is 1/9, a green marble is 1/3, and a yellow marble is 1/2. Which marble is Amanda least likely to randomly select? A. blue B. red C. green D. yellow

Amanda is least likely to pick a blue marble.

Step-by-step explanation:

You have to change the denominator to the same so 18. Blue is 1/18, red would be 2/18 because you have to times 9 by two so you do the same to the numerator. And yellow would be 9/18 because 2 x 9 = 18 and 1 x 9= 9. 1/18 is the least.

Hope this helps :)

A. blue

Step-by-step explanation:

If you want the marble that is least likely to be selected, you just want the fraction that has the biggest denominator.

In this case, it is 1/18, or A. blue

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

do your own work and don"t cheat.
