A container ship left port last week caring some good weighing a total of 125,890 tons today I stopped in another port to unload

11Alexandr11 [23.1K]

Answer:

Step-by-step explanation:

You need to be specific. Did the weight decrease by 60 tons or 60 pounds? I assume tons, but in math, you can't assume.

This problem seems overly simple, so I am wondering if some information is missing. With the given information and assuming the decrease was in fact 60 tons, you would have:

125,890 - 60 = 125,830 tons

2. A two-stage rocket is in development. The required probability is for the overall rocket to be a minimum of 97% reliable for

ikadub [295]

Answer: The minimum reliability for the second stage be 0.979.

Step-by-step explanation:

Since we have given that

Probability for the overall rocket reliable for a successful mission = 97%

Probability for the first stage = 99%

We need to find the minimum reliability for the second stage :

So, it becomes:

P(overall reliability) = P(first stage ) × P(second stage)

$0.97=0.99\times x\\\\\dfrac{0.97}{0.99}=x\\\\0.979=x$

Hence, the minimum reliability for the second stage be 0.979.
