Answer:
98.99%
Step-by-step explanation:
The combined reliability of both components must be 98%. Given that both components must be functional and have the same reliability 'r', the minimum value of 'r' that meets the system requirements is given by:
![0.98 = r^2\\r=0.9899=98.99\%](https://tex.z-dn.net/?f=0.98%20%3D%20r%5E2%5C%5Cr%3D0.9899%3D98.99%5C%25)
The level of reliability required for each component is 98.99%.
Answer:
Catherine's GPA is 2.48
Step-by-step explanation:
A z-score of 2.010 means that Catherine's GPA is 2.01 standard deviations above the mean. Therefore, Catherine's GPA is ![\bar{x}+2.01\sigma=1.963+2.01(0.257)\approx2.48](https://tex.z-dn.net/?f=%5Cbar%7Bx%7D%2B2.01%5Csigma%3D1.963%2B2.01%280.257%29%5Capprox2.48)

Answer:
(x - 25) / 4
Step-by-step explanation:
In this scenario, we have one unknown variable which is the total of the bag of almonds, therefore we can represent this with the variable x. Since Lorenzo ate 25 of this bag we would need to subtract this from the total of the bag. Then we need to divide the remainder by 4 since each of his friends ate the rest in equal parts. This would leave us with the following expression ...
(x - 25) / 4
