Answer:
Step-by-step explanation:
From the given information:
the mean 
= 2300
Standard deviation = 
Standard deviation (SD) = 214.4761
TO find:
a) 
From the Z-table, since 5.595 is > 3.999
P(x > 3500) = 0.0001
b)
Here, the replacement time for the mean 
= 0.25
Replacement time for the Standard deviation 
For 115 component, the mean time = (115 × 20)+(114×0.25)
= 2300 + 28.5
= 2328.5
Standard deviation = 
= 
= 
= 
= 
= 214.482
Now; the required probability:
From the Z-table, since 8.376 is > 3.999
P(x > 4125) = 1 - 0.9999
P(x > 4125) = 0.0001
Hey!
-----------------------------------------------
Solution:
4(9x + 7) = x - 4
36x + 28 = x - 4
36x + 28 + 28 = x - 4 + 28
36x = x + (-32)
36x - x = x - (-24) - x
35x = -32
35x/35 = -32/35
x = -32/35
-----------------------------------------------
Answer:
x = -32/35
-----------------------------------------------
Hope This Helped! Good Luck!
<span>Two numbers that multiply to get 72 but add to get -22
4 x 18= 72
4 + 18 = 22
just change the signs depending on the problem</span>
By applying the variational approach and then comparing the result to the exact solution, we can calculate the error in the approximation. That is the main and major use of Terminal notation of pi.
π/2 = [tex] \lim_{n \to \infty} π (2j)(2j) / (2j-1)(2j+1)
Here, by this expression, we set the limits, and get the approximate error in the experiment.
Hope this helps!
