Explanation

Specific death rate refers to the death rate calculated for a particular segment or subgroup of the population (e.g., by age, sex, cause).

It helps in understanding mortality patterns more precisely than the overall crude death rate.

Explanation

To find Σ(x - 1), first calculate (x - 1) for each value:

(3 - 1) + (1 - 1) + (7 - 1) + (4 - 1)

= 2 + 0 + 6 + 3

= 11

Explanation

The formula ∑x/n calculates the arithmetic mean of a set of numbers, where:

∑x = sum of all values

n = number of values

This formula provides the average value of the dataset.

Explanation

For a leptokurtic distribution, β₂ > 3:

β₂ = μ₄ / μ₂² > 3

Given μ₂ = 3.5:

μ₄ / (3.5)² > 3

μ₄ > 3 × 12.25

μ₄ > 36.75

Explanation

Extrapolation is the process of estimating a value outside the range of known data points.

In contrast, interpolation refers to estimating a value within the known range.

Explanation

Maxwell's equations led to the derivation of the speed of electromagnetic waves, including light.

The speed of light (c) is given by C = 1/√μ₀ε₀, where μ₀ is the permeability of free space and ε₀ is the permittivity of free space.

Explanation

In a reversible adiabatic process, there is no heat transfer (Q = 0).

As a result, the entropy change (ΔS) is zero because entropy change is directly related to heat transfer in a reversible process (ΔS = Q / T).

Explanation

The speed at a banked turn is given by:

v = √(rg tan(θ))

Given v = √(rg), we can equate:

√(rg tan(θ)) = √(rg)

This simplifies to:

tan(θ) = 1

θ = arctan(1) = 45°.

Explanation

The relation between alpha (α) and beta (β) is given by:

β = α / (1 - α)

Given α = 1/2:

β = (1/2) / (1 - 1/2)

= (1/2) / (1/2)

= 1
