Since the sample size is too small (n = 9, which is less than 10) we cannot use the normal model to describe the entire population.
Therefore, we expect the sample mean to be different from the population mean.
Answer:
y= 5.7x-10.7
Step-by-step explanation:
the formula is y=mx+b
Answer:
This system of equations has <em>no solution</em>. It is inconsistent.
Step-by-step explanation:
The last equation tells you z = -1.
Substituting this value for z in the other two equations allows them to be written as ...
-3x -y = 7
-3x -y = 3
There are no values of x and y that can make both these equations true.
