Explanation The given system of equations is { 4 x 2 + 25 y 2 = 21 10 y = 31 − 9 x . The first equation can be write in terms y as follows. 4 x 2 + 25 y 2 = 21 25 y 2 = 21 − 4 x 2 y 2 = 21 25 − 4 25 x 2 y = ± 21 25 − 4 25 x 2 Write the above system equations in terms of y by denoting y 1 , y 2 , and y 3 as follows. { y 1 = 21 25 − 4 25 x 2 y 2 = − 21

The annual aggregate claim amount of an insurer follows a compound Poisson distribution with parameter 1,000. Individual claim amounts follow a Gamma distribution with shape parameter a = 750 and rate parameter λ = 0.25. 1. Generate 20,000 simulated aggregate claim values for the insurer, using a random number generator seed of 955.Display the first five simulated claim values in your answer script using the R function head(). 2. Plot the empirical density function of the simulated aggregate claim values from Question 1, setting the x-axis range from 2,600,000 to 3,300,000 and the y-axis range from 0 to 0.0000045. 3. Suggest a suitable distribution, including its parameters, that approximates the simulated aggregate claim values from Question 1. 4. Generate 20,000 values from your suggested distribution in Question 3 using a random number generator seed of 955. Use the R function head() to display the first five generated values in your answer script. 5. Plot the empirical density…
