The expectation of an exponentially distributed random variable X is equals to 1 / 2. Compute E [ e − 2 x]. I already know that E [ x] of an exponential distribution equals 1 / λ. So λ = 2. I also know that E [ e − 2 x] equals the integral of e 2 x ⋅ f ( x). But when I solve this equation I get ( − 1 / 2) ⋅ ...

If x is a negative number, what is the value of x?

WebIn algebra, a quadratic equation (from Latin quadratus 'square') is any equation that can … WebAnswer (1 of 6): This is a problem involving an erroneous notation. The square root notation is used only for positive square root of a positive real number, and the above equation implies that √x = (2–8)/3=(-2), which in turn implies that x=(-2)^2 =4. But then √x be equal to 2, which leads to a ... holiday bucks at albertsons

Web29 mrt. 2014 · From stem we know that X is negative. Looking for the value of X. 1) x^2=1 x=1 or x=-1 Because the stem tells us that X is negative, we know that x=-1 and therefore this statement 1 sufficient. 2) x^2+3x+2 can be simplified to (x+1) (X+2) which means X=-1 or x=-2 Not sufficient because we have two negative answer choices. Webfor a maximum we should have f ′ ( x) = 0, so that. − sin ( x) + 3 sin ( x) cos 2 ( x) = 0. so finally. { sin ( x) = 0 → f ( x) = 0 cos ( x) = 1 3 → f ( x) = 4 3 3 cos ( x) = − 1 3 → f ( x) = − 4 3 3. which clearly shows the maximum.
