Answer:
For this case the reliability of the sytem would be given by:
R1= 0.95, R2 =0.95, R3= 0.5, R4 = 0.79 , R5 = 0.6
And replacing we got:
Step-by-step explanation:
We can assume that the system work in series
If we have in general n units the reliability of the system is the probability that unit 1 succeeds and unit 2 succeeds and all of the other units in the system succeed. fror n units must succeed for the system to succeed. The reliability of the system is then given by:
For this case the reliability of the sytem would be given by:
R1= 0.95, R2 =0.95, R3= 0.5, R4 = 0.79 , R5 = 0.6
And replacing we got:
Step-by-step Explanation:
First find out what is the price after 30% off.
250 · 0.3 = 75
250 - 75 = 175
Then find the tax and add it on. Remember to calculate the tax AFTER the discount.
175 · 0.06 = 10.50
175 + 10.50 = 185.50
