Answer:
The answer is 4y.
Step-by-step explanation:
First you would solve the parentheses, which would be -1(-3y) which would equal positive 3y, and y+3y=4y. I apologize if I misunderstood the problem ^^
Answer:
This would most probably result in biased sample since only a specific part of the community is being surveyed that does not represent all of the community.
Step-by-step explanation:
A survey is being conducted to determine how a city's residents feel about building a new youth center.
They are considering to survey 50 random children at a local elementary school.
This would most probably result in biased sample since only a specific part of the community is being surveyed that does not represent all of the community.
Moreover, it is likely that the students of elementary school might not even have any interest in youth center so results would be biased.
Therefore, it is suggested to include a variety of samples that is surveying different age groups that covers all of the community.
I think your right,It would be 81.6.
Hope this helps. :D
Answer:
(- 4, 1 )
Step-by-step explanation:
A translation (x + 1), y - 3 ) means add 1 to the original x- coordinate and subtract 3 from the original y- coordinate.
B = (- 5, 4 ), thus
B' = (- 5 + 1, 4 - 3 ) = (- 4, 1 )
