Can the following question be considered a statistical question and why or why not? do students at bryan middle school exercise?

this is a multiple choice question with 4 answers

Yes, it specifies the population

No, it does not specify the population

Yes, it anticipates enough variability in responses

No, it does not anticipate enough variability in responses

I think the answer is (Drum roll please) D.

Step-by-step explanation:

There is not any variability in this question it is just a yes or no question. If the question was "How long does an average person exercise for "

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".
