Let X represent the amount of energy a city uses (in megawatt-hours) in the Kanto region. Let Y represent the amount of mismanaged plastic waste (in metric tons) a city produces in the Kanto region. The following joint distribution relates the probability of a city using a certain amount of energy and creating a certain amount of plastic waste. Remember to list the relevant domains. fxy(x, y) = 2 sy s 2x < 10 2. Find P[X<2UX > 4). TO RECEIVE FULL CREDIT, YOU MUST FIND THE PROBABILITY THROUGH ITEGRATION. Hint: draw the area you are integrating over. You can keep as a fraction or round to one decimal place. 3. Find fy(y) 4. Find E[Y]. Keep as a simplified fraction or round to four decimal places. 5.

Part 2: The probability of X≤2 or X≥4 is 0.5.

Part 3: The value of marginal probability of y is for  

Part 4:The value of E(y) is 4.6667.

Part 5:The value of is for

Part 6:The value of is

Part 7:The value of E(x) is 3.6667.

Part 8:The value of E(x,y) is 36.

Part 9:The value of Cov(x,y) is 18.8886.

Part 10:X and Y are not independent variables as

Step-by-step explanation:

As the complete question is here, however some of the values are not readable, thus the question is found online and is attached herewith.

From the given data, the joint distribution is given as

for

Now the distribution of x is given as

Here the limits for y are So the equation becomes

Part 2:

The probability is given as

So the probability of X≤2 or X≥4 is 0.5.

Part 3:

The distribution of y is given as

Here the limits for x are So the equation becomes

So the value of marginal probability of y is for  

Part 4

The value is given as

So the value of E(y) is 4.6667.

Part 5

This is given as

So the value of is for

Part 6

The value is given as

So the value of is

Part 7

The value is given as

So the value of E(x) is 3.6667.

Part 8

The value is given as

So the value of E(x,y) is 36

Part 9

The value is given as

So the value of Cov(x,y) is 18.8886

Part 10

The variables X and Y are considered independent when

Here

And

As these two values are not equal, this indicates that X and Y are not independent variables.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
