Answer:
contribution margin ratio= 0.37
Explanation:
Giving the following information:
Sales= $4,700
Total variable cost= $2,961
To calculate the contribution margin ratio, we need to use the following formula:
contribution margin ratio= (sales - total variable cost) / sales
contribution margin ratio= (4,700 - 2,961) / 4,700
contribution margin ratio= 0.37
 
        
             
        
        
        
Answer:
Geometric Average return = 7.83%
Explanation:
First we need to find the missing value of data using Arithmetic mean formula
Arithmetic Mean = Sum of value / No of values
8.8% = Sum of Values / 4
Sum of Values = 8.8% x 4
Sum Values = 35.2%
Using Sum of Values we minus the remaining values in order to get the missing value of the data. 
35.20% - 16.3% - 10.2%-(14.1%) = 22.80%
In order to get Geometric mean value we use geometric mean formula
G.M = 4 Sqrt(16.3% x 10.2% x -14.1% + 22.80%)
Geometric Mean = 7.83%

Answer:
The correct answer is letter "A": User Domain.
Explanation:
User Domains are used in organizations with large amounts of servers connected to their network. As it is difficult to keep track of all the data being stored in every server, the domain controller regulates user domains by storing their login credentials but having to pass a privilege screening before accessing to the information of the server. However, that does not secure users will make optimal utilization of the firm's resources. Most parts of the data store will still be unchecked by controllers.
