Answer:
y=3x+5
Step-by-step explanation:
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](https://tex.z-dn.net/?f=0.97%3D0.99%5Ctimes%20x%5C%5C%5C%5C%5Cdfrac%7B0.97%7D%7B0.99%7D%3Dx%5C%5C%5C%5C0.979%3Dx)
Hence, the minimum reliability for the second stage be 0.979.
Answer: a=1.4
Step-by-step explanation:
move the 0.1a to the other and the 7 to the other side which will make the 7 positive and the 0.1a negative.
5a-0.1= 4.9a
-0.14+7=6.86
dive both sides by 4.9 and you get
a=1.4
