Answer:
0.8188 or 82%
0.0000643
Step-by-step explanation:
Given that engineering specifications on the shelf depth of a certain slug to be turned on a CNC lathe are from .0275 in. to .0278 in.
If x is the dimension then X is N(0.0276, 0.0001)
Or
is Normal (0,1)
a) Fraction of shelf depths are in specifications
=
b) For 98% to be within the specifications,

Margin of error = 
For 98% critical value Z two tailed is 2.33
Hence std error = 
So sigma should be = 0.0000643
Answer:
Step-by-step explanation:
Answer:
The error ranges would be the most reliable with a study, all else being equal is:
Option: A is correct.
A. ±6 percentage point.
Step-by-step explanation:
The error range such that the error range is most reliable in the study is:
±6 percentage points.
( Since for the solution to be most reliable the error must be small so that the value is close to the actual value and hence the study is reliable)

In this problem why is the easiest to substitute.
Just set the equations equal to each other because they both equal y
-x + 4 = 2x - 8
(You want to get all the x's to one side so add x to each side)
4 = 3x - 8
(next add 8 to both sides)
12 = 3x
(lastly divide 3 from both sides)
4 = x
You have got your x so now it is time to find that y just replace x to either of the two equations
y = 2(4) -8 or y = -(4) + 4
y = 8 - 8 y = 0
y = 0
Final Answer: y=0, x=4
