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

Answer:

B

Step-by-step explanation:

Since you have the adjacent value, the best way to do this is with tangent. You can do tan(50) = x/3. From there you multiply by 3, and get x = 3(tan50)
