Which statement describes the primary purpose of JavaScript?

cupoosta [38]

a.The primary purpose of JavaScript is to enable features such as validation of forms before they are submitted to the server.

Explanation:

On web pages before submitting the day, end user has to do client validations such as whether data enter is correct data type, so end user for client side validation been eiher by VBSCRIPT (visual basic script language) or (JavaScript java script). Internet explorer or Microsoft edge uses VBSCRIPT for web page validation.

For visual basic script languages end user should have enough knowledge on visual basic programming languages. Same away for java script end user have enough knowledge on c language.

Both Scripts are used for client side validation on success of validation end user will submit web page form for next action. JavaScript is used in most of the browser including Microsoft explorer or Microsoft edge.

What are the value and data type (float, int, bool, or str) of this expression: 5 % 2

amm1812

Answer: float

Explanation:

This is asking what would the remainder be of 5/2. I am not totally sure what you are asking but float is used with remainders because it could have a decimal like 3.33 that would throw an error for anything other than float.

We have said that the average number of comparisons need to find a target value in an n-element list using sequential search is

bija089 [108]

Answer:

Part a: If the list contains n elements (where n is odd) the middle term is at index (n-1)/2 and the number of comparisons are (n+1)/2.

Part b: If the list contains n elements (where n is even) the middle terms are at index (n-2)/2 & n/2 and the number of comparisons are (n+2)/2.

Part c: The average number of comparisons for a list bearing n elements is 2n+3/4 comparisons.

Explanation:

Suppose the list is such that the starting index is 0.

Part a

If list has 15 elements, the middle item would be given at 7th index i.e.

there are 7 indices(0,1,2,3,4,5,6) below it and 7 indices(8,9,10,11,12,13,14) above it. It will have to run 8 comparisons to find the middle term.

If list has 17 elements, the middle item would be given at 8th index i.e.

there are 8 indices(0,1,2,3,4,5,6,7) below it and 8 indices(9,10,11,12,13,14,15,16) above it.It will have to run 9 comparisons to find the middle term.

If list has 21 elements, the middle item would be given at 10th index i.e.

there are 10 indices (0,1,2,3,4,5,6,7,8,9) below it and 10 indices (11,12,13,14,15,16,17,18,19,20) above it.It will have to run 11 comparisons to find the middle term.

Now this indicates that if the list contains n elements (where n is odd) the middle term is at index (n-1)/2 and the number of comparisons are (n+1)/2.

Part b

If list has 16 elements, there are two middle terms as one at would be at 7th index and the one at 8th index .There are 7 indices(0,1,2,3,4,5,6) below it and 7 indices(9,10,11,12,13,14,15) above it. It will have to run 9 comparisons to find the middle terms.

If list has 18 elements, there are two middle terms as one at would be at 8th index and the one at 9th index .There are 8 indices(0,1,2,3,4,5,6,7) below it and 8 indices(10,11,12,13,14,15,16,17) above it. It will have to run 10 comparisons to find the middle terms.

If list has 20 elements, there are two middle terms as one at would be at 9th index and the one at 10th index .There are 9 indices(0,1,2,3,4,5,6,7,8) below it and 9 indices(11,12,13,14,15,16,17,18,19) above it. It will have to run 11 comparisons to find the middle terms.

Now this indicates that if the list contains n elements (where n is even) the middle terms are at index (n-2)/2 & n/2 and the number of comparisons are (n+2)/2.

Part c

So the average number of comparisons is given as

((n+1)/2+(n+2)/2)/2=(2n+3)/4

So the average number of comparisons for a list bearing n elements is 2n+3/4 comparisons.

What is line-level?

Hunter-Best [27]

The maximum strength that an audio signal can be used is line-level.

A. The maximum strength that an audio signal can be.

Explanation:

Line level can be defined as a specified level indicating the strength of an audio signal which transmits analog sound between audio components such as CD players, DVD players, television sets and many more. Usually utilized Voltage and Audio Levels.

A line input level electrical sign ordinarily has a voltage running from 0,3 to 2 Volts, while a receiver level sign is all the more frequently in the range from 5 to 50 mV (millivolts). Most video editors concur that the general sound degree of your sound blend (the entirety of your sound consolidated) ought to be standardized between - 10db to - 20db.
