Hi,
The answer is c. The sample is biased.
This is because the sample is taken on a single state, an Rebecca reports a statistic about the nation. Her data contains information only of her state. If she lives in a very cold state, there is probably more homeowners using electric heat than in a hot state.
It is hard to explain without a picture. You have the line graph and depending on what your numbers are, you place them where the teacher, (or paper) says too. You would then move two to the right, and one up. You would keep repeating that pattern until you got to the top of the graph. After that you would draw a strait line through it. If you are dealing with negative numbers, then depending on which one is negative, you would move two to the LEFT from the starting point and go one up. You repeat that pattern as well, then once you reach the top of the page you draw a line through it.
I hope this helped!

Answer:
Joe is correct
Step-by-step explanation:
Given equation:
The exponent outside the bracket is a question mark and the students are trying to determine the value of the question mark.
For ease of answering, let y be the unknown number (question mark):
First, simplify the equation by applying exponent rules to either side of the equation:
Now, apply the exponent rule:
Therefore,
Finally, solve for y:
Therefore, <u>Joe is correct</u> as the unknown number is 6.
