Statistics QUESTION #2004

Question 6

Using the housework data where employed men spend an average $\mu = 8.2$ hours/week with $\sigma = 2.1$ hours (normal distribution), $P(X \geq 9)$ is found by computing $z$ as:

$z = 0.286$
$z = 0.381$✔️
$z = 0.476$
$z = 0.524$

Correct Answer Logic:

$z = \dfrac{9 - 8.2}{2.1} = \dfrac{0.8}{2.1} \approx 0.381$. Then $P(X \geq 9) = P(Z \geq 0.381) = 1 - \Phi(0.381) \approx 1 - 0.6484 = 0.3516$.

Chemistry QUESTION #4358

Question 11

For the reaction $2A + B \rightarrow 3C + D$, which of the following does NOT express the reaction rate?

$-\dfrac{d[B]}{dt}$
$\dfrac{d[D]}{dt}$
$-\dfrac{1}{2}\dfrac{d[A]}{dt}$
$-\dfrac{1}{3}\dfrac{d[C]}{dt}$✔️

Correct Answer Logic:

Rate $= -\dfrac{1}{2}\dfrac{d[A]}{dt} = -\dfrac{d[B]}{dt} = +\dfrac{1}{3}\dfrac{d[C]}{dt} = +\dfrac{d[D]}{dt}$. The expression $-\dfrac{1}{3}\dfrac{d[C]}{dt}$ is wrong because C is a product so its rate should be positive: $+\dfrac{1}{3}\dfrac{d[C]}{dt}$.

Electrical Engineering QUESTION #2194

Question 19

A synchronous generator with inertia constant $H = 5\,\text{MJ/MVA}$ is rated at $100\,\text{MVA}$. The angular momentum coefficient $M = GH/(\pi f_s)$ used in the swing equation (at $50\,\text{Hz}$) is approximately:

$3.18\,\text{MJ s/rad}$✔️
$5.00\,\text{MJ s/rad}$
$0.318\,\text{MJ s/rad}$
$1.59\,\text{MJ s/rad}$

Correct Answer Logic:

Stored kinetic energy $= H\times S_{rated} = 5\times100 = 500\,\text{MJ}$. Swing equation inertia: $M = \frac{GH}{\pi f_s} = \frac{100\times5}{\pi\times50} = \frac{500}{157.08} \approx 3.18\,\text{MJ·s/rad}$.
