1) through: (2, 3), parallel to y = 4x - 1
2) through: (5, -4), parallel to y = -
3/5x +1
3)through: (1, 2), parallel to y = 6x + 3
4)through: (-1, -1), parallel to y = -4x + 1
answers=
1)y = 4x - 5
2)y = -
3/5-1
3) y = 6x - 4
4)y = -4x - 5
17/5
13/6
that should be right
Answer:
What is the question. Please provide a question.
Answer: 106.5
Step-by-step explanation:
We know that, Confidence interval for population mean is given by :-
( Sample mean - Margin of error , Sample mean + Margin of error)
Given: confidence interval is (92.3, 120.7).
i.e. Sample mean - Margin of error = 92.3 (i)
Sample mean + Margin of error = 120.7 (ii)
Adding (i) and (ii) , we get
2( Sample mean ) = 213
⇒ Sample mean = 106.5
Hence, the sample mean = 106.5
