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:
The formula of a volume of a cylinder:
r - radius
H - height
We have r = 3in and H = 9in. Substitue:
Answer:
Step-by-step explanation:
let the distance from central pole to one end=r
8/r=tan 40°
r=8/tan40=8 cot~40°=8 cot(90-50)=8 tan ~50≈9.534
2r≈19.068≈ 19.1
width of tent=19.1 ft
Common difference = 6 - 2.5 = 3.5
(B) recursive formula can be written as
U(n+1) = U(n) + 3.5n
where value of n is 0 to infinity
Definitions
Independent events= one outcome of an event doesn’t affect the other outcomes
Dependent events= one outcome of an event affects the other outcomes
Examples
Independent= Jack has a standard deck of cards 52 cards( 26 red and 26 black) what is the probability that he picks a red card or a spade?
Dependent= Jack has a standard deck of cards. What is the probability that he picks a red card or a diamond?
