Slope=rise/run
rise=-15 feet (since it's downhill)
run=24 feet
slope=-15/24=-5/8
slope=-5/8
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:
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)
