A figure shows a trapezoid drawn inside a triangle. The area of the trapezoid is 96 mm², and the area of the triangle is 125 mm². A point on the figure is randomly selected, and its location recorded. After 250 trials, the randomly selected point was in the trapezoid 154 times.

How does the experimental probability of a randomly selected point being in the trapezoid compare to the theoretical probability of the event?

The experimental probability of the event is choose and the theoretical probability of the event is choose. Therefore, the experimental probability is choose the theoretical probability.

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".
