Consider the office renovation project data in Table 7.16. A“zero” time estimate means that the activity could take a verysmall amount of time and should be treated as a numericzero in the analysis.a. Based on the critical path, find the probability ofcompleting the office renovation project by 39 days.b. Find the date by which you would be 90 percent sure ofcompleting the project.
Determine the Critical Path first - then crash until in All-Crash Mode using this information: Activity Predecessor Normal time Normal cost Crash time Crash cost Max Crash Time Slope A - 12 $200 9 $350 B A 8 $300 8 $300 C A 9 $250 7 $450 D B 6 $400 5 $600 E B,C 5 $150 4 $225 F C 10 $500 9 $650 G D,E,F 8 $400 6 $900 What to do: Duration Activities Crashed Incremental Crash Cost Cumulative Crash Cost How many days saved?

Can i get help with the question below please and thank you 16) This could be a rover, probe/satellite, manned mission, telescope, etc. This mission must be accomplished using technology that is available today (no Warp or Epstein drives) and must be accomplished within your lifetime. Your mission will not be a copy of a real mission. Constraints: ▪ Answer using the underlined subheadings at each point below (Mission Objective, Target, Instrumentation), marks will be deducted for poorly organized answers. ▪ You target must be reachable by whatever you are sending within a human lifetime (~75 years), it would be nice to visit Gliese 581c, but it is 20 light years from Earth so for now it is unreachable. What this means is that you are constrained to our solar system except for telescopes that peer into the universe or a probe getting to interstellar space. ▪ If your mission includes sending humans, then we need to estimate a reasonable limit on how far we can send humans. For our…
