Match the following quotes from well-known individuals to one of the three perspectives: Radical, Conservative, or Liberal. Quote 1: "Capitalism does not permit an even flow of economic resources. With this system, a small privileged few are rich beyond conscience, and almost all others are doomed to be poor at some level. That's the way the system works. And since we know that the system will not change the rules, we are going to have to change the system." - Martin Luther King Jr., Civil Rights Leader [ Select ] Quote 2: "We have been ruled by men who live by illusions...the illusion that there is some other way of creating wealth than hard work and satisfying your customers." - Margaret Thatcher, Former British Prime Minister [ Select ] Quote 3: "You cannot separate the political structure from the economic structure. One has to be an idiot to believe that the average working person who's making $10,000 or $12,000 a year is equal in political power to somebody who is the head of a large bank or corporation. So if you believe in political democracy, if you believe in equality, you have to believe in economic democracy as well." - Bernie Sanders, U.S. Senator [ Select ] Quote 4: "It was the labor movement that helped secure so much of what we take for granted today. The forty-hour work week, the minimum wage, family leave, health insurance, Social Security, Medicare, retirement plans. The cornerstones of middle-class security all bear the union label." - Barack Obama, Former U.S. President [ Select ]

a. (2 Points) The PIC16F886 used in Labs supports 35 instructions over 3 categories of instructions. 2 of those categories, split into byte and bit instructions, have 2 lengths of opcodes: 6 bits for byte instructions and 4 bits for bit instructions. Using these 2 sizes of opcodes, and assuming all the opcodes can be used, how many instructions in total could be supported between byte and bit instructions?

Solve clearly and careful for the answer will vote down if used AI !!!!Two identical three-phase, Y-connected synchronous generators equally share a load of 10 MW at 33kV and when combined on the load the machines have a combined 0.8 power factor lagging. The mechanical power driving both machines is equal. One of the machines supplies 125 A of lagging current. Calculate the current provided by the second machine. [Calculate the combined current at PF=0.8 lagging. Each machine provides P=5MW, show that the PF of the machine supplying 125A is PF=0.7lag, the current supplied by the second machine is the difference. Answer: (97)/(-)25.62deg _(A).] 7.

(a) Let xi, i = 1,2, ...,n be a sample. Define Yi = axi + b for some constants a and b. What is therelationship between the means ~ and y? What is the relationship between the standard deviations S and Sy? Feel free to use the results from class, but show all work!(b) A sample of temperatures has a mean of 92.1deg F with a standard deviation of 3.4deg F. Use the result from part (a) and the relationship F = 1.8C + 32 between degrees Fahrenheit and degrees Celcius to find the mean and standard devation of the sample in degrees Celcius.I have also included some slides from class for (a) otherwise just do without those Mean Mean Example: The weights (in pounds) of six horses are measured by a The sample mean of n observations 1, 2,...,, is veterinarian. Horse 1 2 3 4 6 Weight 600 627 645 679 693 671 n n There are n=6 horses.The observations are =600,x=627 X3=645,x4=679,x5=693,and6=671. Note that the mean of two numbers is the number right in the middle of them. In general, you can think of the mean as the "balancing point" of the data. The mean weight of the six horses is =652.5~653 Ibs 6 Note that the mean has the same units as the observations. All of the observations must be in the same units in order for the mean to make sense! Mean The mean is a "measure of central tendency." It is supposed to represent the "average" observation, the value that most closely aligns with most of the observed values. Mean On a histogram or stemplot, an outlier is usually visible as an observation far away from the densest part of the distribution. However, the mean can be changed, sometimes drastically, by observations whose values are much smaller or larger than the rest of the observations. Such observations are called outliers. Example: The heights in inches of ten individuals is measured 67.7, 64.9, 68.4, 68.2, 64.1, 81.4, 64.6, 66.8, 67.1, 68.0 Let's add another horse to our data whose weight is 1231 pounds Horse 1 2 3 4 5 6 7 Weight 600 627 645 679 693 671 1231 The mean of these observations is 67.6 inches. That's a big horse! So we have a new observation x7 = 1231 What is the mean of this new set of observations? Mean We can see that the mean has been pulled away from the highest density area to the right towards the outlier. The mean of the new data set with the extra large horse is 600+627+645+679+693+671+1231 ~735 Ibs 7 The mean increased by almost a hundred pounds! Is it still a good representation of most of the observations? Outliers are a type of influential observation because they have a strong influence on the mean value We say that the mean is not a resistant measure of central tendency, because it can be so heavily influenced by outliers
