The failure rate for a guided missile control system is 1 in 1,000. Suppose that a duplicate but completely independent control
1 answer:
Answer:
The reliability is approximately 0.999999.
Step-by-step explanation:
The control system for a guided missile has a failure rate of 1 in every 1,000.
Therefore, the likelihood of the missile functioning successfully is .
In the newly structured system, if the first one fails, the backup can take over.
There are two outcomes possible: either the first fails or it works.
If the first is successful, the probability is = 0.999.
If the first one fails, the probability becomes .
The overall reliability of the modified missile is 0.999 + 0.000999 = 0.999999.

Answer: La probabilidad que necesitamos es 0.16.
Step-by-step explanation:
Se nos proporciona que
La probabilidad de que el estudiante sea un senior = 0.22
La probabilidad de que el estudiante tenga una licencia de conducir = 0.30
La probabilidad de que el estudiante sea un senior o tenga una licencia de conducir = 0.36
Buscamos la probabilidad de que el estudiante sea un senior y tenga licencia de conducir.
Según la pregunta,
Por lo tanto, la probabilidad que necesitamos es 0.16.
<span>Starting with the equation f = v + at
Subtract v on both sides:
f - v = at
Divide both sides by a:
(f - v) / a = t
Swap the sides:
t = (f - v) / a
</span>
Subtract v on both sides:
f - v = at
Divide both sides by a:
(f - v) / a = t
Swap the sides:
t = (f - v) / a
