Answer:
the client could expect a maximum loss of -0.054/year (-5,4%/year)
Step-by-step explanation:
since the 68-95-99.7 rule states that states probability that the anual return stays between 1 standard deviation from the mean is 68% , 2 standard deviations → 95% and 3 standard deviations → 99.7%
Then we are almost certain that the annual return will stay between 3 standard deviations from the mean.
Thus the most a client can loose is approximately at 3 standard deviations from the mean = 0.066 - 3*0.04 = -0.054 (-5,4%/year)
A^2+b^2=c^2
8^2+b^2=17^2
64+b^2=289
b^2=225
b=15
The TV would be 14 inches tall.
( I used Pythagorean theorem )
note: TVs are advertised by the length going diagonally across
the opposite is squared so,
square root of 4 is 2 and 2 squared is 4
Answer:
Correct answer: x₁ = 1 / √3 = √3 / 3 or x₂ = - 1 / √3 = - √3 / 3
Step-by-step explanation:
Given:
3 x⁴ + 14 x² - 5 = 0 biquadratic equation
this equation is solved by a shift x² = t and get:
3 t² + 14 t - 5 = 0
t₁₂ = (-14 ± √14² - 4 · 3 · 5) / 2 · 3 = (-14 ± √196 + 60) / 6
t₁₂ = (-14 ± √256) / 6 = (-14 ± 16) / 6
t₁ = -5 or t₂ = 1 / 3
the solution t₁ = -5 is not accepted because it cannot be x² = -5
we accepted t₂ = 1 / 3
x² = 1 / 3 ⇒
x₁ = 1 / √3 = √3 / 3 or x₂ = - 1 / √3 = - √3 / 3
