A machine cuts N pieces of a pipe. After each cut, each piece of pipe is weighed and its length is measured; these two values are then stored in a matrix with two columns (first the weight and then the length on each row of the matrix). Ignoring units, the weight is supposed to be between 2.1 and 2.3, inclusive, and the length is supposed to be between 10.3 and 10.4, inclusive. Write a script that counts how many rejects there are. A reject is any pipe that has an invalid weight and/or length. For a simple example, if N is 3, the matrix could look like: a. 2.14 b. 10.30 c. 2.32 d. 10.36 e. 2.20 f. 10.45

1. you have a small business that is divided into 3 departments: accounting, sales, and administration. these departments have the following number of devices (computers, printers, etc.): accounting-31, sales-28, and administration-13. using a class c private network, subnet the network so that each department will have their own subnet. you must show/explain how you arrived at your conclusion and also show the following: all available device addresses for each department, the broadcast address for each department, and the network address for each department. also, determine how many "wasted" (not usable) addresses resulted from your subnetting (enumerate them).

What are the 12 colors of the spectrum called?
