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
The seventh child is fourteen years and seven month.
Let A be the number of Adult tickets and S, the Students'
A+ S = 273, but we know that S=2.A
Then A + 2A = 273 ; 3A =273; A =273/3 =91
So 91 tickets were sod to Adults & 182 Tickets to Students
Step-by-step explanation:
We can break this up into pieces, first we do, 7/8 - 1/4, find the least common denominator which is 8, so the equation will be 7/8 - 2/8, which we can now subtract and will give us, 5/8, now that we have done that, we can do 5/8 - 1/2. Since we know that half of 8 (our denominator) is 4. Then the equation would be 5/8 - 4/8, which brings us to 1/8 as our final answer.
