Answer:
D. Last_modified
Explanation:
Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.
Some of the models used in the software development life cycle (SDLC) are;
I. Waterfall model.
II. Incremental model.
III. Spiral model.
IV. Agile model.
V. Big bang model.
VI. V-shaped model.
A database schema is a structure which is typically used to represent the logical design of the database and as such represents how data are stored or organized and the relationships existing in a database management system. There are two (2) main categories of a database schema; physical database schema and logical database schema.
Last_modified can be defined as a data type which comprises of the date and time that a resource such as a software application or file was edited or changed.
Hence, Last_modified is a reasonable data type that could be included in nearly any item in a logical data model for a software application.

Answer: Time Division Multiple Access (TDMA)
Explanation:
Time Division Multiple Access (TDMA) is a digital cellular telephone communication technology which allow many users to share the same frequency without interference. It works by dividing a signal into different timeslots, and increasing the data carrying capacity.
Time Division Multiple Access (TDMA) is a complex technology since it requires accurate synchronization between the transmitter and the receiver. Again, TDMA is used in digital mobile radio systems. The individual mobile stations cyclically assign a frequency for the exclusive use of a time interval.
In most instances, the entire system bandwidth for an interval of time is not assigned to a station. But the frequency of the system is divided into sub-bands, and TDMA is used for the multiple access in each sub-band. Sub-bands are referred to as carrier frequencies and the mobile system that uses Sub-bands are known as the multi-carrier systems.
Consider this illustration, the frequency band has been shared by three users. Each user is assigned definite timeslots to send and receive data. user ‘2' sends after user ‘1’ and user ‘3’ sends thereafter. More users can be added too.
From the question, Time Division Multiple Access (TDMA) are developed to improve the efficiency and quality of digital communications and it can divide a channel into six or more time slots.
0.61 (rounded up)
Explanation:
You add both 700 and 450 which will give you 1150g
You then divide 1150 by 100 which gives you 11.5
Then divide 7 by 11.5 which will give you 0.61 as cost of every 100 grams
