2.Provides assessment opportunities Provides assessment opportunities to determine benchmark digital literacy proficiencies, measure student progress, growth and achievement on formative and, finally, summative levels

3.Differentiates, adapts, and personalizes instruction Differentiates, adapts, and personalizes instruction based upon group or individual student needs—including ability to re-sequence content or provide differentiated instruction to students for remediation or acceleration.

5.Engages students with a balance of online and offline activities

6.Promotes important learning in ways other formats can’t including interactive content, audio, video, auto-scored instruction and assessments, online grade books, and reports. Assuming the curriculum will be delivered online, it should be regularly updated based on changing skill needs as well as student and educator feedback.

7.Saves time, especially for busy educators. Student and teacher should be able to access and use the curriculum intuitively or with minimal training. If delivered online, the curriculum contains auto-scored instructional and assessment content, an online dashboard, grade book, and reports for individual students, classes, schools. and district.

8.Provides technical and instructional support for educators that is accessible via interactive chat, phone, and email or similar help so that their questions can be addressed quickly.

olga55 [171]

Answer:Packet and circuit switching

Explanation: Packet switching is the technique through which the data is sent from the source to destination in the form of data packets on dynamic path.It is the time of connectionless switching and route generates for each packet.

Circuit switching is the switching technique having connected path for the sending and receiving of the data.They have well defined and established path for the transmission of data.

Other options are incorrect because they define the terms that are associated with the data that gets transmitted like bandwidth,transmission rate ,packet etc. These options are not the way in which data transmitted or switched.Thus, the correct option is packet and circuit switching.

Consider the following relation: CAR_SALE (Car#, Date_sold, Salesman#, Commision%, Discount_amt Assume that a car may be sold by

Nady [450]

Answer:

See explaination

Explanation:

The given relation is:

CAR_SALE(Car#, Date_sold, Salesperson#, Commission%, Discount_amt)

Primary key: {Car#,Salesperson#}

We will first check whether the relation is in 1NF.

A relation is said to be in the 1st Normal form(1NF) if all the columns in the relation have atomic values. In this case, the relation is in 1NF.

A relation is said to be in the second normal form(2NF) if it satisfies the condition that all non keys are completely dependent on the primary key and just a part of the primary key.

In the case of the CAR_SALE relation, the Commission% depends only on the Salesperson# and not on the combination of Car# and Salesperson#. This means that the given relation is not in 2NF. To satisfy 2NF, we make two relationships as given below:

SALE_DETAIL(Salesperson#, Commission%)

and CAR_SALE(Car#, Date_sold, Salesperson#, Discount_amt)

Now both the relations are in 2NF.

For a relation to be in 3NF, no non-key should be functionally dependent on another non key.

In the case of the CAR_SALE relation, it is specified that the Date_sold field determines the Discount_amt. Therefore the modified CAR_SALE is not in 3NF.

To satisfy 3NF, we seperate the non key and the dependent non key and create a different table.

Final Relations:

SALE_DETAIL(Salesperson#, Commission%)

Discount_Detail(Date_Sold, Discount_Amt)

CAR_SALE(Car#, Date_sold, Salesperson#)
