Directions: In column B, labeled ID#, assign each student a unique ID#. These numbers should start at 123 and run consecutively through 150. You should not type each number individually (use fill). If any student is missing an assignment, the cell should be red. This should update automatically (don’t manually shade it red). Calculate the current grade as a percentage. The Current grade column should only look at grades that have been submitted to the gradebook. (ignore empty cells) Note: All assignments are not equally weighted. Calculate the finale grade as a percentage. The Final grade column treats all grades as being submitted (0’s are computed for omitted work). Compute the students current letter grade. The Letter grade column is based off of the Current grade and should update automatically as assignments are graded. Report the count for how many students fall into each grade cut point. This should update automatically as grades are input. Calculate the class rank. Rank should be calculated such that each student has a unique rating based off of current grade and ties should be broken based on location. (Whatever is listed first is ranked first) Calculate Averages, ranges, and Medians for All assignments and percent grades.

Which statement is true of web-based social media? a.they allow consumers to interact with and update content. b.they cannot be updated easily, as compared to print media. c.they are expensive to produce and maintain, as compared to print and television. d.they can exist independent of the internet.

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx,fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx,fs) does automatic scaling and then calls sound(xx,fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2
