Answer:
Mean= 5.70
Standard deviation= 0.132
Step-by-step explanation:
For the distribution of sample mean:
Mean of the sampling distrubution = \mu = 5.70
Standard deviation of the sampling distrubution = sigma/sqrt{n} = 1.7201 /sqrt{170} = 0.132
Answer: Negative slope:

Step-by-step explanation:
(3, -2) satisfies both equations. 3-2=1, and -3-2=-5.
Answer:
3y √21 + 2 y√15
Step-by-step explanation:
To simply, we open up the bracket
We have this as;
√(189y^2) + √60y
= 3y √21 + 2 y√15
