I just know the answer is 28
Answer: option B
Step-by-step explanation:
i took the test lol
The equation is of the form y = mx + c, where m is the slope and c just a constant. In this example, m=-5 and c=-2/3, so the slope is -5. The -2/3 is just a vertical offset and is irrelevant.
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%
3x + 2y = 39
-3x -3x
2y = 39-3x
— ———
2 2
y= 19.5 - 3x/2
plug (19.5 - 3x/2) for y
1.5x - 2(19.5 - 3x/2)= 39
x= 17.33333333334
