Answer:
(a) E(X) = 3
(b) Var(X) = 12.1067
Explanation:
(a) E[X]
E[X]T = E[X]T=A + E[X]T=B + E[X]T=C
= (2.6 + 3 + 3.4)/3
= 2.6 (1/3) + 3(1/3) + 3.4(1/3)
= 2.6/3 + 1 + 3.4/3
= 3
(b) Var (X) = E[X²]−(E[X])²
Recall that if Y ∼ Pois(λ), then E[Y 2] = λ+λ2. This implies that
E[X²] = [(2.6 + 2.6²) + (3 + 3²) + (3.4 + 3.4²)]/3
= (9.36 + 12 + 14.96)/3
= 36.32/3
= 12.1067
Var(X) = E[X²]−(E[X])²
= 12 - 3²
= 12.1067 - 9
= 3.1067
B) Step 2: Assess the national business environment is part of which step in the screening process for potential markets and sites.
The national environment of a business consists of economic, demographic, natural, cultural and political forces.

A state-owned enterprise is a company that operates within the borders of a particular country. Like local companies, state-owned companies understand the culture of the country and develop products and services to satisfy the market. For example, Donut Time is a donut shop that operates throughout Australia.

Answer:
a. 863
Explanation:
Calculation for the order quantity
Order quantity = 75 x (10 + 2) + (1.64 x 8) - 50
Order quantity = (75 x 12) + (1.64 x 8) - 50
Order quantity= 900 + 13.12 - 50
Order quantity= 863.12
Order quantity = 863
Therefore the Order quantity will be 863
Answer:
decreases
increases
Explanation:
Nominal interest rate is real interest rate plus inflation rate. If nominal interest rate rises, people would prefer to save their money and so the demand for money would fall.
Real income is income adjusted for price level changes. The higher the real income,the higher the purchasing power, the higher the demand for money.
