This is an example of a systematic sample.
Dr. Jon developed a system in order to get a random sample. His plan was to survey the 4th student that entered his classroom.
Answer:
Correct, as 4 is the only number repeating twice
8k-4k+4+7-k =
8k-4k-k+4+7 =
3k+11
The answer is b. Great job! here ill show you the work.
15x +90 > 270
move constant to the right side and change its sign, like this:
15x>270-90
then subtract the numbers
15x>180
lastly, divide both sides by 15.
hope this helped!
