Answer:
The overall reliability of the system is 99.9952%
Step-by-step explanation:
Probability of the system not working:
None working, the first with 2% probability of not working(as it has 98% probability of working), the second with 4% and the third with 6%. So
0.02*0.04*0.06 = 0.000048
Probability of the system working:
1 subtracted by the probability of the systme not working.
1 - 0.000048 = 0.999952
0.999952*100% = 99.9952%
The overall reliability of the system is 99.9952%
Answer:
x = 6
y = 4
Step-by-step explanation:
x + x - 2 = 10
2x - 2 = 10
2x = 12
x = 6
y = 6 - 2
y = 4
<span>1. Cross multiply:
4 * x + 18 = 7 * 28
Simplifying
4 * x + 18 = 7 * 28
2. Reorder the terms:
4 * 18 + x = 7 * 28
18 * 4 + x * 4 = 7 * 28
72 + 4x = 7 * 28
3. Multiply 7 * 28
72 + 4x = 196
Solving
72 + 4x = 196
Solving for variable 'x'.
4. Move all terms containing x to the left, all other terms to the right.
5. Add '-72' to each side of the equation.
72 + -72 + 4x = 196 + -72
6. Combine like terms: 72 + -72 = 0
0 + 4x = 196 + -72
4x = 196 + -72
7. Combine like terms: 196 + -72 = 124
4x = 124
Divide each side by '4'.
8.Simplifying
x = 31
