The EPA sets national air-quality standards for common air pollutants. The data table shows the change in concentrations of these pollutants over time.
Which conclusion do the data support?

A. Monitoring concentrations of pollutants is too expensive.
B. With monitoring, the concentration of every pollutant has
decreased.
O c. With monitoring, the concentration of every pollutant has
increased.
D. Monitoring concentrations of pollutants has been ineffective.

Given a link with a maximum transmission rate of 32.8 mbps. only two computers, x and y, wish to transmit starting at time t = 0 seconds. computer x sends filex (4 mib) and computer y sends filey (244 kib), both starting at time t = 0. statistical multiplexing is used, with details as follows packet payload size = 1000 bytes packet header size = 24 bytes (overhead) ignore processing and queueing delays assume partial packets (packets consisting of less than 1000 bytes of data) are padded so that they are the same size as full packets. assume continuous alternating-packet transmission. computer x gets the transmission medium first. at what time (t = ? ) would filey finish transmitting? give answer in milliseconds, without units, and round to one decimal places (e.g. for an answer of 0.013777 seconds you would enter "13.8" without the quotes)
