Task-4: Plot a scatter plot with the Model Year values in the x-axis and their value counts in the y-axis. Make sure the plot has proper labels and title. [Hint: You can use Series.index attribute to have model year as a data sequence]. Comment on your observations in a following markdown cell. 59]: #GIVE YOUR ANSWER FOR TASK-4 IN THIS CELL model_year_data-pd.DataFrame(model_year) plt.scatter(ev_pop[ "Model Year'], model_year_data[ 'Model Year'])

The video below shows a series of fireworks explosions, but was recorded in slow motion at 240 frames per second. You can see the audio sound track pictured at the bottom of the video. Use make measurements from the video to determine the speed of sound. a. describe how you determined the distance from the explosion to the camera.   b.Here is some data from a nearby weather station on the night of the fireworks. The video was recorded at about 10:30 PM.  Does this cause you to revise your calculations above?

Suppose we have an input image f(x,y) shown below. 0 1 2 3 4 2 2 2 2 2 2 4 5 6 7 0 1 2 3 4 0 0 1 5 7 Plese compute the gradient at point (2,3) (Write ansewer in the first blank) (2,4) (Write answer in the second blank) (3,3) (Write ansewer in the third blank) (3,4) (Write answer in the fourth blank) using Sobel Operator. gradient (x,y) =|Gx|+|Gyl.
