The answer is here in the picture
X+7=2+3
Simplify both sides of the equation.
x+7=2+3
simplify step-by-step.
x+7=(2+3)(Combine Like Terms)
x+7=5
Subtract 7 from both sides.
x+7−7=5−7
Answer:
(a): Marginal pmf of x
(b): Marginal pmf of y
(c): Mean and Variance of x
(d): Mean and Variance of y
(e): The covariance and the coefficient of correlation
Step-by-step explanation:
Given
<em>x = bottles</em>
<em>y = carton</em>
<em>See attachment for complete question</em>
<em />
Solving (a): Marginal pmf of x
This is calculated as:
So:
Solving (b): Marginal pmf of y
This is calculated as:
So:
Solving (c): Mean and Variance of x
Mean is calculated as:
So, we have:
Variance is calculated as:
Calculate
So:
Solving (d): Mean and Variance of y
Mean is calculated as:
So, we have:
Variance is calculated as:
Calculate
So:
Solving (e): The covariance and the coefficient of correlation
Covariance is calculated as:
Calculate E(xy)
This gives:
So:
The coefficient of correlation is then calculated as:
--- approximated

Answer is 15
Step-by-step explanation:
Half of 40 is 20 cause 40/2=20
Five less than 20 is 20-5 which= 15
So ur answer is 15
