The answer is in this site but it doesn’t let me copy and paste here so ill drop it in here https://www.bartleby.com/solution-answer/chapter-22-problem-19e-probability-and-statistics-for-engineering-and-the-sciences-9th-edition/9781305251809/human-visual-inspection-of-solder-joints-on-printed-circuit-boards-can-be-very-subjective-part-of/d33fbd51-5636-11e9-8385-02ee952b546e
Well Group 1 is 30
Group 2 is 10
Group 3 is 30.
So Group 2 is most biased
Answer:
x = 35, x = 27
Step-by-step explanation:
(9)
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
141° is an exterior angle, thus
x + 24 + 2x + 12 = 141 , that is
3x + 36 = 141 ( subtract 36 from both sides )
3x = 105 ( divide both sides by 3 )
x = 35
-----------------------------------------------------------
(11)
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
2x - 9 + 3x + 2x = 180
7x - 9 = 180 ( add 9 to both sides )
7x = 189 ( divide both sides by 7 )
x = 27
4 + 7
This is equivalent because you cannot subtract integers and must add the opposite for example
13 - (-10)
and when we add the opposite the question now looks like this
13 + 10
