Suppose that a system requires 2 parts in order to work. Based on past similar systems, you assume that after 1 year the probability the first part will still be working is .75, .50 for the second part, and .85 that at least one of the parts will still be working. What is the probability that you would estimate that the system still works after 1 year?

Answer #1

Answer:

Given that:

Suppose that a system requires 2 parts in order to work. Based on past similar systems, you assume that after 1 year the probability the first part will still be working is 0.75, 0.50 for the second part, and 0.85 that at least one of the parts will still be working

A=1st part is still working

B=2nd part is still working

To find ,since both A and B has to happen for the system to work

We have a system that has 2 independent components. Both components must function in order for the system to function. The first component has 9 independent elements that each work with probability 0.92. If at least 6 of the elements are working then the first component will function. The second component has 6 independent elements that work with probability 0.85. If at least 4 of the elements are working then the second component will function. (a) What is the probability...

A systems specialist has studied the workflow of clerks all doing the same inventory work. Based on this study, she designed a new workflow layout for the inventory system. To compare the average production for the old and new methods, a random sample of 6 clerks was used. The average production rate (number of inventory items processed) for each clerk was measures both before and after the new system was introduced. The results are shown below. Test the claim that...

PLEASE ANSWER ALL PARTS AND SHOW ALL WORK! In this section, all collisions will be completely elastic – that is, the total kinetic energy of the system will be constant throughout. Also, the collisions are entirely one-dimensional, with all motion taking place in either the northward or southward direction. The setting: a room with a frictionless floor. A block of mass 1 kg is placed on the floor and initially pushed northward, whereupon it begins sliding with a constant speed...
