For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points through which the line passes:

We found the slope:

Substituting we have:

Thus, the equation is of the form:

We substitute one of the points and find the cut-off point:

Finally, the equation is:

ANswer:

The first one -8-13-18
calculate it
2. (-1,4) because it’s the only point in the intersection of both intersections. All the other points only fall into the solution of one inequality or in the case of 4 none
Given 10 independent part,
No mean shift
This implies that,
The mean is 10
It also means that the variance is 0
And also the standard deviation is 0.
Then, the sigma deviation is
3×0+10=10.
Since none of the data is at such a high point, the manufacturing testing process has not yet reached three-sigma quality levels.
Since we have this let use the special consideration
Three-sigma limits set a range for the process parameter at 0.27% control limits. Three-sigma control limits are used to check data from a process and if it is within statistical control
Therefore,
The 0.27% will give the defective
2.7/100×10=0.027
Then, the none defective is
1-0.027=0.973
Which is 97.3%
