questions
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
Okay so your answer would be 9
Answer:
d. The population standard deviation is known.
Step-by-step explanation:
T-distribution or Z-distribution, which to use?
