The fire department in california decided to take a poll to see if residents would pay a monthly fee for their services. they polled 22 people in the state and concluded that residents were not willing to pay a monthly fee. what is wrong with this poll?
a)the conclusion is based on a bad sample.
b)the conclusion is based on reported results.
c)the conclusion is based on a small sample.
d)the conclusion is based on a voluntary response sample.

c. The conclusion is based on a small sample.

Step-by-step explanation:

Given : The fire department in California decided to take a poll to see if residents would pay a monthly fee for their services.

To survey a whole state the sample size must be enough large so that it would be able to represent the entire population which helps to make the conclusion after survey more reliable and accurate to the researcher .

But they only polled 22 people in the state and concluded that residents were not willing to pay a monthly fee.

Since 22 is a very small sample size to represent the entire population , so it would have large chances get inaccurate results.

Thus, the wrong thing with this poll is "The conclusion is based on a small sample."

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".

i can you with this sweetie!
