Answer:
P(0, 1)
Step-by-step explanation:
Using the section formula
=
=
= 0
=
=
= 1
Hence P(0, 1)
Answer:
x = 15
Step-by-step explanation:
Create a proportional relationship to solve for x
3/2 = x/10
Cross multiply
2x = 30
Divide both sides by 2
x = 15
let's put value of t in equation.
x = 2√t
x = 2√y
x/2 = √y
(x/2)^2 = y
y = x^2 /4
now let's differentiate it with respect to x.
dy/dx = 2x/4 = x/2
differentiating again wrt to x
d^2y/dx^2 = 1/2
Answer:

And we can find the second moment with this formula:

And replacing we got:

And we can find the variance like this:
![Var(X) = E(X^2) -[E(X)]^2= 189.72- (13.22)^2 =14.9516](https://tex.z-dn.net/?f=%20Var%28X%29%20%3D%20E%28X%5E2%29%20-%5BE%28X%29%5D%5E2%3D%20189.72-%20%2813.22%29%5E2%20%3D14.9516)
And the deviation would be:

Step-by-step explanation:
For this case we have the following dataset given:
Payment $7 $9 $11 $13 $15 $17
Probability 0.18 0.08 0.09 0.16 0.08 0.41
For this case we can calculate the mean with this formula:

And replacing we got:

And we can find the second moment with this formula:

And replacing we got:

And we can find the variance like this:
![Var(X) = E(X^2) -[E(X)]^2= 189.72- (13.22)^2 =14.9516](https://tex.z-dn.net/?f=%20Var%28X%29%20%3D%20E%28X%5E2%29%20-%5BE%28X%29%5D%5E2%3D%20189.72-%20%2813.22%29%5E2%20%3D14.9516)
And the deviation would be:
