Interviews withconstruction engineers analyzing the risks involved ledto the estimates that such an explosion would occur withprobability 0.25 as a result of static electricity, 0.20 as aresult of malfunctioning of equipment, 0.40 as a result ofcarelessness, and 0.75 as a result of sabotage. It is alsofelt that the prior probabilities of the four causes of theexplosion are 0.20, 0.40, 0.25, and 0.15. Based on all thisinformation, what is(a) the most likely cause of the explosion;(b) the least likely cause of the explosion?For 30 recent Academy Award ceremonies, ages of Best Supporting Actors (x) and ages of Best Supporting Actresses (y) are recorded.The 30 paired ages yield x¯ = 52.1 years, y¯ = 37.3 years, r = 0.076, P-value = 0.691, and y^ = 33.4 + 0.0587x.

- I need fast plz I give up vote .Incorrect and incomplete solution will be down votedEngr. Janry Garcia and Engr. Caroline Moncada is working on a project for a newly constructed 4-story building. The project is regarding CCTV installation. As project engineers, they need to assess and make an inventory of the primary materials to be installed in the building. The following primary materials give the merchandise with its corresponding price list. C=CCTV Camera worth P5000 each; W=Cable wires P100 per meter; S=Splitters worth P50 each and B=Balun and Connectors for P150. Each of the materials should be distributed depending on the number of units per floor. For the 1st floor: twice the number of CCTV cameras is needed, three times the length of cable wire is required, four times the number of splitters and five times the number of baluns and connectors less is necessary, which gives an acceptable loss of -60dB. For the 2nd floor: 6 times the number of CCTV cameras are required, seven times the length of cable wire is needed, eight times the number of splitters less and…
