We can classify the system by seeing if it’s consistent and independent. So that’s how you would classify the system.
Hopefully this helps!
Answer:
The sample size needed to be taken is approximately 74.
Step-by-step explanation:
To get alpha; we have 1 - 0.95 = 0.05
Therefore, 
The we look up z* in a Standard Normal table where α = 0.025 area in each tail.
From the table, z* = 1.96
From the question variance is 484, then the standard deviation is 22
Standard deviation = 
And margin of error is 5 or less
The formula for margin of error is given as:
margin of error = 

The approximate value of n is 74.
Answer:
y-1=
(x+8)
Step-by-step explanation:
1. y-y1=m(x-x1) (point slope form)
2. y1 is the y of your given point and x1 is the x of your given point
3. m is the slope
