Design and implement an application that has 5 text boxes, a button (make its text SORT) and a label. (example: copy the PushCounterPanel. java code and call it ’PushCounterPanelSorter. java’) The user can enter 5 different numbers using the 5 text boxes. When the user clicks the SORT button, sort the 5 numbers using any of the sorting algorithms we learned in class and display the numbers separated by comma using the label for showing the output: -a sorted list.

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.

1. which of the following statements are true about routers and routing on the internet. choose two answers. a. protocols ensure that a single path between two computers is established before sending packets over it. b. routers are hierarchical and the "root" router is responsible for communicating to sub-routers the best paths for them to route internet traffic. c. a packet traveling between two computers on the internet may be rerouted many times along the way or even lost or "dropped". d. routers act independently and route packets as they see fit.

3. write assignment statements that perform the following operations with the variables a, b, and c: a. adds 2 to a and assigns the result to b b. multiplies b times 4 and assigns the result to a c. divides a by 3.14 and assigns the result to b
