Question Solved1 Answer Language: C++ Write a class named car that has the following private member variables: yearModel: An int that holds the car's year model make: A string that holds the make of the car speed: An int that holds the car's current speed In addition, the class should have the following public member functions: Constructor: Accepts two arguments. The first argument is the car's year model, and the second argument is the car's make. These values should be assigned to the yearModel and make member variables. This constructor should assign 0 to the speed field. Default Constructor: Sets the yearModel member variable to 2022, sets the make member variable to an empty string (""), and sets the speed member variable to 0. set YearModel: Accepts an int argument that is assigned to the yearModel member variable. The function returns no value. setMake: Accepts a string argument that is assigned to the make member variable. The function returns no value. setSpeed: Accepts an int argument that is assigned to the speed member variable. The function returns no value. getYearModel: Returns the value stored in the yearModel1 member variable. getMake: Returns the value stored in the make member variable. getSpeed: Returns the value stored in the speed member variable. accelerate: Adds 5 to the speed member variable. The function returns no value. brake: Subtracts 5 from the speed member variable. The function returns no value. Note: Write only the class declaration for the car class. Do not write a main function, and do not write any #include directives.

1) Use one of those datasets: Kansas City Crime Data (Links to an external site.) Medicare Utilization (Links to an external site.) Chicago Taxi Trip History (Links to an external site.) 2) I addition pick any publicly available dataset that may be combined with a dataset of your choice from the list above. As we learned that the wrangling techniques may differ depending on the goal of future analysis. 3) Come up with a specific analytical question that can be theoretically answered with the combination of one the datasets listed above and another public dataset that you've identified. 4) Conduct the appropriate data wrangling that will help to prepare both datasets or their combination for data analysis keeping in mind the analysis question. Use either Python or SAS. For more information on the latter, see these SAS instructions (Links to an external site.). Submit a short Word description of the steps you have been following and the rationale behind each of them in respect to the choice of the solutions and their connection to the question. Also, attach the processed dataset(s) and Python or SAS script that has been used.

Please write your answer in python Define a function called sasquatch(), which has one parameter. Name the parameter whatever you want The function should print the value of its parameter to the console. Additional Notes: Regarding your code's standard output, CodeLab will check for case errors and will check whitespace (tabs, spaces, newlines) exactly.

Part A: • a=[H202) in the reaction vessel x=[S2032-1/2 in the reaction vessel (the theory is described in the first few pages of Exp. 4 in the Lab Manual) HINT: How much volume is in the reaction vessel? The reaction vessel is the beaker in which solution A is made and into which solution B is added. Both solutions A & B must be present for the reaction to take place. • You should realize that, for x = 0, In[(a)/(a-x)] = 0 and Time= 0. (0, 0) is thus a valid data point, and you should explicitly include this point when using Excel to generate the linear Trendline for the plot of In[(a)/(a-x)] vs Time. This is entered in the first data row of the table. Furthermore, for this particular trendline, you must select the "Format Trendline" option: "Set intercept = 0" to require the line to pass directly through (0,0). Part A: Spreadsheet Headings Table Solution V H202 MH202 a v s2032- MS2032- x a-x Time(s) In(a/(a-x)) ID 0 o AB1 2.5 0.025 2.5 0.01 84.8 AB2 5.0 0.025 2.5 0.01 41.2 AB3 10.0 0.025 2.5 0.01 19.5 AB4 2.5 0.025 1.0 0.01 28.5 AB5 2.5 0.025 2.0 0.01 60.0 AB6 2.5 0.025 3.0 0.01 95.2 AB7 2.5 0.025 4.0 0.01 145.5 • Note that the volumes of reagents given in this Prelab Exercise should be similar to those you will actually be required to use during the lab (as indicated in your lab manual). • Plot the graph of In(a/(a-x)) vs Time. Note that, in Excel, the column on the left (Time) will, by default, correspond to the x-axis. • Use "Chart Options" to title, label the x-y axes and data points appropriately. • View the spreadsheet and graph in "View Page Break Preview", to ensure that the data and graph are contained within the 1st page. Resize your Part A graph suitably. • Insert a trend line with the intercept set to zero and with the equation of the line displayed on the graph. • Label the points using the "Chart Options/Data Labels" feature. Select or enter the labels that will make point recognition easiest.

# Statistics Null Hypothesis: # paired t-test # Pl ans carefully according to question Q-1 Q-2 Q-3 Q-4 #Pl ans all You have the following data on average number of cats per 1000 citizens in different cities in 2000 and 2020 years (all data is artificial). city 2000 2020 Moscow 300 350 New York 320 370 Beirut 200 240 Minsk 700 750 You want to answer the question: are there any statistically significant changes in the number of cats per 1000 citizens in these two years. Let us try two-sample t-test first. Consider values in columns 2000 and 2020 as two independent samples, apply two- sample t-test with symmetrical alternative and enter p-value obtained. Enter numeric value with 3 digits after the decimal point. Now let us consider difference between 2020 in 2000 for each city. city 2000 2020 diff Moscow 300 350 50 New York 320 370 50 Beirut 200 240 40 Minsk 700 750 50 Let us model numbers in the last column as an i.i.d. sample from some random variable X. Our null hypothesis is that there are no systematic changes between 2020 and 2000 and all the differences are just due to random flukes. What is the expected value of X provided that null hypothesis holds? Now let us use 1-sample t-test to test null hypothesis that values in column "diff" are obtained from population (random variable) with zero mean. Use symmetric alternative. Find p-value. Enter 4 digits after the decimal point. Now let us apply paired t-test to our initial samples. Use function scipy.stats.ttest_rel that do exactly this. Enter p-value (4 digits after the decimal point).

please do both please 3. When they work together, Jerry and Leo can do their weekly house chores in 58 minutes. When Leo works alone he can finish the chores in 12 minutes less time than Jerry. When Jerry works alone, how long will it take him to do the weekly chores in the house? 4. For each pair of functions determine where the zeros of the original function occur and state the equations of the vertical asymptotes of the reciprocal function. If no zeros exist, state so. a) 9(t)= 7 - 131+30 b) j(w) x2 + 1
