Suppose that engineering specifications on the shelf depth of a certain slug to be turned on a CNC lathe are from .0275 in. to .
MrRa [10]

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 \frac{x-0.0276}{0.0001} is Normal (0,1)

a) Fraction  of shelf depths are in specifications

=P(0.0275

b) For 98% to be within the specifications,

\mu = 0.02765

Margin of error = 0.0278-0.02775\\=0.00015

For 98% critical value Z two tailed is 2.33

Hence std error = \frac{0.00015}{2.33} \\=0.0000643

So sigma should be = 0.0000643

3x+1+5x=7+15+7x what is x?
LenKa [72]

Answer: x=21

Step-by-step explanation:

To solve for x you must first combine you like terms on each side of the equal sign. So you problem will become 8x+1=22+7x. Then get your x on one side and your numbers on the other by taking the one away from the right side and 1 away from 22. Then take away 7 from the left side to cancel it out. Then take 7x away from 8x to leave you with x. making your answer x=21
