if a six-sided die is rolled 30 times, how many times can you expect to get a 6?
a.3
b.5
c.6
d.10

5 times a 6 can be expected in 30 times.

Step-by-step explanation:

A die is rolled 30 times.

We have to find how many time a 6 can be expected in 30 times.

Probability of getting 6 in 1 time =

⇒ Probability of getting 6 in 30 time =

                                                             = 5 times

Therefore, 5 times a 6 can be expected in 30 times.

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".

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
