Question 1 Below, you are provided with the firm-level demand, marginal revenue, and relevant cost curves for Knight Trucks. Knight Rider produces electric pick-up trucks in the monopolistically competitive pick-up truck market. Suppose, initially, that this graph depicts the scenario in which trucks are not traded internationally. $,1 (in thousands) Part (i): Suppose that the United States does not trade electric pick-up trucks internationally. Identify the profit-maximizing number of electric trucks that Knight Rider will sell, as well as the profitmaximizing per-truck price that Knight Rider will charge. Part (ii): Suppose that the United States does not trade electric pick-up trucks internationally, and that Knight Rider produces and sells the quantity that you identified in part (i). How much profit does Knight earn? What does this tell you about whether there is currently an incentive for new firms to enter the domestic electric pick-up truck market, or for existing firms to exit this market?

The mean of three numbers, num1, num2, and num3, is given by meanOfThree = \frac{(num1 + num2 + num3)}{3.0}. Read double variables num1, num2, and num3 from input, respectively. Then, compute meanOfThree using the formula. Finally, output "Mean is" followed by the value of meanOfThree to four digits after the decimal point. End with a newline. Ex: If the input is 30.0 33.0 21.0, then the output is: Mean is 28.0000 1 #include <iomanip> 2 #include <iostream> 3 using namespace std; 4 5 int main() { 6 7 double num1; 8 double num2; 9 double num3; 10 double MeanOfThree; 11 12 cin >> num1; 13 cin >> num2; 14 cin >> num3; 15 16 meanOfThree = (num1 + num2 + num3) / 3.0; 17

Final Project: Consider the databases EEG signal data "EEG Normal" and "EEG Seizure". Curve length: This equation is useful in predicting the stability of the values of a signal. If, in a given interval, the value of this feature is low, it is indicative that the signal is stable; otherwise, the signal is unstable. We calculate this using: CL = ZN = 1/(N-1) * Î£(xi+1 - xi) (1) Root mean square: This equation is defined as the square root of the mean of the squares of the values of the signal. The root mean square (also known as quadratic mean) is determined by: RMS = âˆš(1/N * Î£(xi^2)) (2) N is equal to the total number of samples for each column. Using Visual Basic, calculate the equations (1) and (2) for each column. Visualize the results obtained. Explain if there is any difference in the results obtained per column within a database, and when comparing between the two databases.
