Answer: Biased sample
Step-by-step explanation:
This is a biased sample because only students with strong opinions are likely going to volunteer or show interest in representing the school at the board meeting. This sample is a voluntary type sample, and at such the conclusion is not valid. This sample is biased because a group or population of students have a higher or lower sampling probability.
Answer:
1 ans 6
2 ans 4
3 ans 8
because if x equals zero then its basic arithmetic
Answer:
-0.9090... can be written as 
.
Explanation:
Any <em>repeating </em>decimal can be written as a fraction by dividing the section of the pattern to be repeated <em>by </em>9's.
We can start by listing out
0.909090... = 9/10 + 0/100 + 9/1000 + 0/10000 + 9/100000 + 0/1000000 + ...
Now. we let this series be equal to x, that is
= 9/10 + 0/100 + 9/1000 + 0/10000 + 9/100000 + 0/1000000 + ...
Now, we'll multiply both sides by 100
.
= 90 + 0 + 9/10 + 0/100 + 9/1000 + 0/10000 + ...
Then, subtract the 1st equation from the second like so:
= 90 + 0 + 9/10 + 0/100 + 9/1000 + 0/10000 + 9/100000 + 0/1000000 + ...
= - 9/10 - 0/100 - 9/1000 - 0/10000 - 9/100000 - 0/1000000 - ...
And we end up with this:
Finally, we divide both sides by 99 in order to isolate x and get the fraction we're looking for.
Which can be reduced and simplified to

Hello there,
1st attachment:
So in order to find this answer. We need to know that in a CUBE there is L*W*H. Your answer would be A.) 1125 because when we do 1125 3 times (L*W*H). . . It give's us 3375.
2nd attachment:
Your answer would be D.) 5,832m³.
My reason I say this is because when you do 18 square root to 3. It will give you 5,832m³
3rd attachment:
Your correct answer would be 80mm³. So this is what I did. C wouldn't be the wrong answer because that answer is in "inches" and we want to find the answer in "mm³" So when we do 2*2*2. We get 8cm. We need to find the answer in "mm³" "8cm" converted in "mm³" would equal 80mm³.
Hope this helps.
