Suppose in a class of 100 students, there is a homework due every week. The professor wants to encourage students to hand in their homework early so, for each homework, he gives extra credit to the first 25 students who turn their homework in. The professor wants to have a record of which students get the extra credit for each week. So, for each week, he stores the list of 25 students who will get extra credit for that week.(a) The professor decides to store the results of each week by saving a list of PIDs of the students who got the extra credit. i. How many bits are required to store each result (each list consists of 25 PIDs and one PID is a string with 9 characters and each character can be stored as an 8-bit ASCII code.)? ii. If 1 KB is 8,192 bits, how many weeks of this data can the professor store? iii. Come up with a more efficient way to store PIDs using the fact that the first character is either A or U and the following 8 characters are digits (0,1,...,9).) Show that storing PIDs this way, the professor can almost triple the number of weeks he can store on 1 KB. (b) Devise an encoding scheme that can fit 100 weeks of data into 1 KB. (Describe the scheme and also how many bits you need for each week of data.)

hi, you. i think this we be deleted because it's a invalid question.

(i suggest no to do this in the

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.
