App that tells you the answers to your homework

Math can be a challenging subject for many learners. But there is support available in the form of App that tells you the answers to your homework. Multi protocol label switching (MPLS) networks have been running well for more than 20 years because applications are centrally hosted in the data center. However, if these applications are moved to different places, the traditional network may not be the best way to connect users to the applications. This will seriously affect performance, user experience and ultimately enterprise productivity. This app can take notes, draw and write by hand, and even record the teacher's lecture content for listening to again when reviewing.

At this time, we need to pay attention to English, mathematics and professional courses, and increase the review of political courses. Because of the early review time of English, most students have memorized the words twice and brushed them once in the previous stage. At this time, as long as the frequency of learning words and long and difficult sentences is maintained, it is enough to appropriately increase the number of reading real questions, and 2-3 can be done in a day. Mathematics can buy learning materials, combine textbooks with reference books, cultivate problem-solving ability, exercise thinking speed and problem-solving quality.

We need to find a solution to maximize the log likelihood function. When using a numerical solver, we do not need to calculate the derivative and manually solve the parameters of the maximum log likelihood function. Just implement a function that we want to maximize and pass it to the numerical solver. Since most solvers in Python aim to minimize a given function, we implement a function that calculates the negative log likelihood function (because minimizing the negative log likelihood function is the same as maximizing the log likelihood function).

This problem is not that you know how to analyze and convert, but that you have done similar problems. [answer] a. Analysis: calculate the growth of the average of each business income compared with the previous year. Since the options give percentages, the average growth rate is obtained.
