Answer:
![E(X) =\sum_{i=1}^n X_i P(X_i)](https://tex.z-dn.net/?f=%20E%28X%29%20%3D%5Csum_%7Bi%3D1%7D%5En%20X_i%20P%28X_i%29)
Replacing the values that we have:
![1 = 0.98*a + 0.02(a-42) = 0.98a +0.02a -0.84](https://tex.z-dn.net/?f=%201%20%3D%200.98%2Aa%20%2B%200.02%28a-42%29%20%3D%200.98a%20%2B0.02a%20-0.84)
And solving for a we got:
![1.84 = a](https://tex.z-dn.net/?f=%201.84%20%3D%20a)
So then the premium value for the insurance on this case should be 1840 dollars.
Explanation:
For this case we can define the random variable X as the gain ( in thousand of dollars) of insurance company
We assume that the premium clase charge and amount of a to the company and we know from the info given that:
![p(X=a) = 1-0.02 = 0.98](https://tex.z-dn.net/?f=%20p%28X%3Da%29%20%3D%201-0.02%20%3D%200.98)
![p(X = a-42) = 0.02](https://tex.z-dn.net/?f=%20p%28X%20%3D%20a-42%29%20%3D%200.02)
represent the expected gain in thousand of dollars
The expected value of a random variable X is the n-th moment about zero of a probability density function f(x) if X is continuous, or the weighted average for a discrete probability distribution, if X is discrete.
And using the definition for a discrete random variable we know that :
![E(X) =\sum_{i=1}^n X_i P(X_i)](https://tex.z-dn.net/?f=%20E%28X%29%20%3D%5Csum_%7Bi%3D1%7D%5En%20X_i%20P%28X_i%29)
Replacing the values that we have:
![1 = 0.98*a + 0.02(a-42) = 0.98a +0.02a -0.84](https://tex.z-dn.net/?f=%201%20%3D%200.98%2Aa%20%2B%200.02%28a-42%29%20%3D%200.98a%20%2B0.02a%20-0.84)
And solving for a we got:
![1.84 = a](https://tex.z-dn.net/?f=%201.84%20%3D%20a)
So then the premium value for the insurance on this case should be 1840 dollars.
Answer:
B) Favourable Variances occur whenever actual prices or actual usage of inputs are greater than standard prices or standard usage.
Explanation:
Variances refer to the difference between actual and standard or budgeted costs. Standard cost is also referred to as budgeted cost. Budgeted costinh can be used by a food nutritionist to determine the food quantity he can cook as well as the ingredient amount which consists of the budgeted costs and the actual cost of preparing the food. Budgeted costchas a major advantage which is its ability to determine the pricing policy even before the product or service is delivered. When favourable or unfavourable variances are mentioned, it refers to the greater of budgeted or actual price or quantity. Favourable goes with a greater actual price or quantity while unfavorable or adverse goes with a greater standard price or quantity.
