Library Sciences QUESTION #1548

Question 788

Douglas McGregor's Theory X assumption about library employees holds that:

Employees are self-directed, creative, and seek responsibility
Employees inherently dislike work, avoid responsibility, and must be coerced and controlled to perform✔️
Employee motivation depends primarily on salary levels
Employees are motivated primarily by social relationships at work

Correct Answer Logic:

McGregor's Theory X assumes employees are inherently lazy, dislike work, and need close supervision and coercion. Theory Y, by contrast, assumes employees are self-motivated. Library managers drawing on Evans et al. (2007) are encouraged to adopt Theory Y approaches to foster professional growth and staff engagement.

Physics QUESTION #4398

Question 794

The time in which half of the given number of radioactive nuclei decay is known as:

$\dfrac{1}{2}$ life of radioactive element✔️
$\dfrac{2}{3}$ life of radioactive element
$\dfrac{1}{4}$ life of radioactive element
$\dfrac{2}{5}$ life of radioactive element

Correct Answer Logic:

Half-life ($t_{1/2}$) is defined as the time required for half ($50\%$) of the radioactive nuclei in a sample to decay. It is given by $t_{1/2} = \dfrac{0.693}{\lambda}$ where $\lambda$ is the decay constant.

Statistics QUESTION #2002

Question 795

Using the same company data (800 employees, 160 degree holders, 272 managers, 80 are both), the conditional probability $P(\text{college graduate} \mid \text{manager})$ is:

$\dfrac{80}{160}$
$\dfrac{80}{272}$✔️
$\dfrac{272}{800}$
$\dfrac{160}{272}$

Correct Answer Logic:

$P(\text{grad} \mid \text{manager}) = \dfrac{P(\text{grad} \cap \text{manager})}{P(\text{manager})} = \dfrac{80/800}{272/800} = \dfrac{80}{272} \approx 0.294$. This is the definition of conditional probability.

Economics QUESTION #1692

Question 798

In the IS-LM model of macroeconomic equilibrium, the LM curve traces out all combinations of income and interest rates at which:

The goods and services market is in equilibrium
The government budget is balanced
The money market (financial market) is in equilibrium✔️
None of these

Correct Answer Logic:

The LM curve (L = Liquidity preference, M = Money supply) represents all combinations of real income (Y) and interest rate (r) at which the money market is in equilibrium — where money demand equals money supply ($L(Y, r) = M/P$). As income rises, money demand increases, requiring a higher interest rate to maintain equilibrium. The IS curve represents equilibrium in the goods market.
