59 degrees!
because you set up your problem: 3c+2+2c-7=90
then combine all like terms: 5c-5=90
Add 5 to both sides: 5c=95
then divide both sides by 5: c=19
Plug in your answer: 3(19)+2=59

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.
