Question 2: | A biometric system consists of two subsystems: face and fingerprint. The following values have been obtained for the two subsystems separately: FMR (False Match Rate) FNMR (False Non-Match Rate) Face subsystem Fingerprint subsystem 8% 10 % 4% 14% Suppose that the subsystems decisions are combined as follows: The outcome of the combined system will be a match only when the outcomes of both of the subsystems are matches. When the outcome of either subsystem is a non-match, the outcome of the combined system will be a non-match. a. Compute the FMR and FNMR values of the combined system? b. What are your conclusions about the performance of the combined system?

Kevin plans to employ a Boolean operator as he is inclined towards investigating two discrete fields of study. It is imperative for Kevin to utilise the appropriate Boolean operator during the process of conducting a search in order to obtain dependable outcomes.
1. The decision tree (hierarchy) below was constructed to help decide which, among several types of computers, should be purchased. The weights were decided upon by the prospective buyer who was looking for a new computer. Note that all the criteria are objective and can easily be quantified except reliability which has been rated by an expert on a scale from 1 to 10, with 1 being very reliable and 10 being very unreliable.

Correct answer will be upvoted else Multiple Downvoted. Computer science. All sections between two houses will be shut, in case there are no instructors in the two of them. Any remaining sections will remain open. It ought to be feasible to go between any two houses utilizing the underground sections that are open. Educators ought not reside in houses, straightforwardly associated by an entry. Kindly assist the coordinators with picking the houses where educators will reside to fulfill the security necessities or establish that it is unimaginable. Input The originally input line contains a solitary integer t — the number of experiments (1≤t≤105). Each experiment begins with two integers n and m (2≤n≤3⋅105, 0≤m≤3⋅105) — the number of houses and the number of sections. Then, at that point, m lines follow, every one of them contains two integers u and v (1≤u,v≤n, u≠v), depicting a section between the houses u and v. It is ensured that there are no two sections…
