Q1 True/False (each needs a quick justification)

Q1(a) Binomial(100, 0.2) approximated by Normal N(20,16)

Steps:

  1. Identify: X ~ Bin(n=100, p=0.2).

  2. Compute mean: μ = np = 100(0.2) = 20.

  3. Compute variance: σ² = np(1−p) = 100(0.2)(0.8) = 16.

  4. Rule: For large n, Binomial ≈ Normal with same mean/variance (CLT-ish approximation).

  5. Conclusion: Yes, approximate with N(20,16).

Q1(b) MAP estimator equals argmax log posterior

Steps:

  1. MAP definition: θ̂MAP = argmaxθ f(θ|x).

  2. Taking log

Geothermal energy is the heat energy stored within the Earth. This heat originates mainly from:

  • Residual heat from the Earth’s formation

  • Heat generated by radioactive decay of elements like uranium, thorium, and potassium

Geothermal energy can be harnessed for electricity generation, space heating, industrial processes, and direct heating applications. It is considered a renewable, reliable, and environmentally friendly energy source.

2. Nature of Geothermal Fields

A geothermal field is...

1. FCFS (First Come First Serve) Scheduling

FCFS is a non-preemptive CPU scheduling algorithm where processes are executed in the order of their arrival. The process that arrives first gets the CPU first. It is simple to implement using a queue. However, it can cause long waiting time and convoy effect.

---

2. SJF (Shortest Job First) Scheduling

SJF selects the process with the shortest CPU burst time for execution....

Iris Marion Young (1949–2006) was a pioneering political theorist who significantly reshaped contemporary debates on justice by moving beyond a narrow focus on the distribution of goods to a deeper analysis of oppressive social structures and institutional power. She argued that injustice is embedded in everyday practices, norms, and decision-making processes rather than merely in unequal allocation of resources. Her influential concept of the “five faces of oppression”—exploitation,

Biomass Conversion Techniques

Biomass consists of organic materials such as animal dung, agricultural waste, crop residues, and biodegradable waste. Biomass energy is obtained by converting these materials into useful forms of energy.

Types of Biomass Conversion Techniques:

(a) Thermochemical Conversion

  • Combustion: Direct burning of biomass to produce heat and power.

  • Gasification: Partial combustion producing combustible gases.

  • Pyrolysis: Heating biomass without oxygen to obtain bio-oil, gas,

Polymorphism and its Methods

(12 Marks – Fully Expanded Answer)

Polymorphism

Polymorphism is one of the most important features of Object Oriented Programming (OOP).
The word polymorphism is derived from two Greek words:
Poly means many and Morph means forms.

Therefore, polymorphism means one name having many forms.

In C++, polymorphism allows the same function or operator to perform different operations in different situations.


Need of Polymorphism

  • Improves code flexibility

  • Reduces complexity
