HELP PLEASE!! Explain what might have gone wrong in the following situation:

Sandra is putting together a new computer and network out of used parts. She has sufficient parts that should work together—NIC card, cables, hub, etc.—and all of them are functional by themselves, but somehow her computer is not successfully able to connect to the network. What might be going wrong?

The “rule of 72” is used to approximate the time required for prices to double due to inflation. if the inflation rate is r%, then the rule of 72 estimates that prices will double in 72/r years. for instance, at an inflation rate of 6%, prices double in about 72/6 or 12 years. write a program to test the accuracy of this rule. for each interest rate from 1% to 20%, the program should display the rounded value of 72/r and the actual number of years required for prices to double at an r% inflation rate. (assume prices increase at the end of each year.)
