Answer:
flat tax is a set percentage that dies not change
graduated tax changes according to the amount being taxed. usually, the higher the amount, the higher the tax rate is.
Answer:
Explanation:
Let we assume the number of CD produced be X
So, the total cost would be
C = Fixed cost + variable cost × number of CD produced
= $30,000 + $17X
For total revenue, it would b
R = $63X
For total profit, it would be
P = Selling cost per CD × number of CD produced - variable cost per CD × number of CD produced - fixed cost
= $63X - $17X - $30,000
= $46X - $30,000
For number of CD, it would be
0 = $46X - $30,000
X = $30,000 ÷ $46
= 652 CD for break-even
Answer: false
Explanation:
Vulnerability assessment is defined as the systematic and methodical evaluation of security posture of the enterprise. It is used to expose the assets to the things that can harm them.
The steps that are involved in vulnerability assessment are the identification of asset, threat evaluation, the vulnerability appraisal, the risk assessment and finally the risk mitigation.
Therefore, the question is false
Answer:
18 years
Explanation:
Given that;
P= $23,000
A= $76,300
r= 6.7%
From
A = P(1 + r/100)^n
76,300 = 23,000 (1 + 0.067)^n
3.3 = (1.067)^n
Taking logarithm of both sides
log 3.3 = log (1.067)^n
log 3.3 = nlog(1.067)
n= log 3.3/log 1.067
n= 0.5185/0.0282
n= 18 years ( to the nearest year)
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
