Determine the covariance for the joint probability density function f subscript X Y end subscript (x comma y )space equals space c times x times y over the range 0 < x < 16 and 0 < y < x. Hint: you need to first find the value of c using the second property in eq. (5.2) of the textbook, and then the expected values of X, Y, and XY using equations (5.3), (5.4), and (5.14), and the covariance from (5.15). Calculate up to 2 decimal points.

question:

could we have options?

i pretty sure it is

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
