Answer: Random fluctuations.
Explanation: Time series is a series that has all the points of time in a equal time order.So, there is usually organised and having equal gaps sequence. It can be imposed on many data like real value data, discrete data,continuous data . But there is no space for the space of randomness so, random fluctuations are not predictable in it.Therefore the option (D) is the correct option.
Answer:
SUMIFS
Explanation:
As we know that the excel is used to present the data in a very attractive way by applying the formulas, pie charts, functions as a pivot table, goal seeking, macros, etc
In order to determine the total sales for each and every sales person, production and location combination we use the SUMIFS function so that the total of each column could come in an easiest and better way
Answer: B) Transport layer
Explanation:
The transport layer is basically responsible for the flow control and detecting the error recovery between the system.
In the open system interconnection, the transport layer are responsible for transferring of data independently along with the congestion control, flow control, segmentation and error control.
And the presentation layer, session layer, physical layer and application layer in the OSI model are nor responsible for the flow control in the network system.
Therefore, option (B) is correct option.
