Answer:
B.
Explanation:
Fixed costs are those costs which are not output dependent. Are fixed till certain level of output. The fixed cost per unit changes with output.
Variable costs are those costs which are output dependent. There is a positive correlation between the production output and the variable cost. The variable cost per unit remains constant.
With the classification of cost into fixed and variable, the manager can count the break even point, in amount terms as well as in the number of unit terms.
The ratio between the variable cost and fixed cost shows how much adjustable is the organization.
Answer:
cyber fraud.
Explanation:
Cyber fraud can be regarded as one the numeeous type of cybercrime fraud, it could be a deception or tricks in the use the Internet just to defraud people, stealing of victims information and other valuables.

Consumers make that affect the decisions of the suppliers.
Range is the measure of variation that is very sensitive to extreme values. It is the difference between high and low values, while standard deviation is the standard measure of variation.The range rule of thumb roughly estimates the standard deviation of a data set as s=range/4 , where s stands for standard deviation and
<span>range = Maximum - Minimum</span>
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
