Consider the scenario described by the statement " A customer can make many payments, but each payment is made by only one customer." Use this scenario as the basis for an entity relationship diagram (ERD) representation.

Least square fit to polynomial write a function leastsquarefit3pol that solves a linear system of equations to find a least squares fit of a third order polynomial to an experimental data set given as two row arrays. the function leastsquarefit3pol must explicitly solve a set of linear equations and cannot use polyfit. there should be no restriction on the size of the problem that can be solved.

You have been supporting csm tech publishing's windows server 2016 server network for over a year. the office has two windows server 2016 servers running active directory and a number of other roles. management has informed you that a small sales office is opening in the same building three floors up. the sales manager wants to install a sales application on a server located in the sales office. this server will have limited physical security because there's no special room dedicated for it, which means it will be accessible to non-it personnel and visitors. you're considering installing windows server 2016 server core on the new server because accessing its console regularly probably won't be necessary, and this server will be managed from one of the other csm tech publishing servers. what are the benefits and drawbacks of using server core for this branch office? what are some things you should do to set up this server management environment?
