Answer: Its coefficient of variation = 0.316
Step-by-step explanation:
The formula to find the coefficient of variations:
Coefficient of variation:
Given: Asset X has
Variance = 10
Expected return = 10
then, coefficient of variation
Hence, its coefficient of variation = 0.316
The answer would be 30 degrees because points F, G, H, and J are collinear, all you would have to do is figure out /_GHK by subtracting 180 degrees from it.
Like this :
JHK = 180 degrees - 120 degrees = 60 degrees
Answer:
(3, 6 ) and (- 3, 18 )
Step-by-step explanation:
Equate the right side of both equations, that is
x² - 2x + 3 = - 2x + 12 ← subtract - 2x + 12 from both sides
x² - 9 = 0 ← in standard form
(x - 3)(x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x + 3 = 0 ⇒ x = - 3
Substitute these values into f(x) = - 2x + 12
f(3) = - 2(3) + 12 = - 6 + 12 = 6 ⇒ (3, 6 )
f(- 3) = - 2(- 3) + 12 = 6 + 12 = 18 ⇒ (- 3, 18 )
