Answer:
Yes, The overall cost of wiring in addressable fire alarm system is significantly cheaper than the conventional one.But the addressale fire alram system is more reliable than a conventional system.
Explanation:
Conventional systems are hardware-based and use analog technology. where addressable fire alarm use digital technology. addressable system is generally more reliable than a conventional system mainly due to how the different systems are wired. With a conventional system, if a device’s wire is damaged or severed, its signal and the signal of other devices down the line cannot be transmitted to the control panel.
With an addressable system, both ends of the wire connect to the control panel. Therefore, if one end becomes damaged or severed, signals can still reach the control panel through the other end of the loop. In addressable systems, a device can be removed or disabled and it will not affect the other devices in the loop.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
Betty is developing a machine learning algorithm that looks at a vast amount of data that is collected over 100 years, and She also wants to check the relationship among variables such as humidity, temperature, and rainfall in the given data.
So, the correct answer to this question is b. She is developing an association machine learning algorithm.
Because the association tells the relationship between variables. She used the association to find the relationship among variables such as humidity, temperature, and rainfall.
While the other options are not correct because:
Regression is used to find out the cause and effect relationship between dependent and independent variables. Big data is the biggest field of data analysis, so this option does not best suit this context. Classification is used to classify data, or organizing data into their related group. While clustering is the task of dividing the population into a number of groups such that populations in the same groups are more similar to other populations in the same group than those in other groups. so these are all incorrect options to this question except the "b" option i.e association.
