Which of the following questions will most likely be answered by displaying data on a line graph?

1 answer:

4 0

It would be A because B could be answered best with a poll graph, C with a pie graph, and D with a bar graph. Line graphs typically show speed and rate so A makes the most sense, but you are still able to do the other questions on a line graph.

The default print setting for worksheets is________

frez [133]

Answer:

Print Active Sheets .

Explanation:

This question refers to the default printing system of the Excel program. Thus, when printing a job using this program, the default option will print all the active sheets, that is, all those spreadsheets where information has been entered. To be able to print in another option, such as selecting certain cells, rows or columns, you must configure the printing for this purpose.

You open a folder Properties box to encrypt the folder, click Advanced, and discover that Encrypt contents to secure data is dim

yaroslaw [1]

Most likely a virus has attacked the system and is disabling encryption is the most likely problem.

c. Most likely a virus has attacked the system and is disabling encryption.

Explanation:

The end users can protect the folder by enabling encrypt the folder or files. But in windows encrypting the file or folder is not available. The computer management console is used to open all other services such as risk management, performance management extra.

In some other operating encryption of folder or files is allowed. Third-party software is available to protect folder or files once the third party used any files possible to share outside the world.

As far as my knowledge there is encrypting technology is available in the windows operating system.

It takes 2 seconds to read or write one block from/to disk and it also takes 1 second of CPU time to merge one block of records.

Alexxx [7]

Answer:

Part a: For optimal 4-way merging, initiate with one dummy run of size 0 and merge this with the 3 smallest runs. Than merge the result to the remaining 3 runs to get a merged run of length 6000 records.

Part b: The optimal 4-way merging takes about 249 seconds.

Explanation:

The complete question is missing while searching for the question online, a similar question is found which is solved as below:

Part a

For optimal 4-way merging, we need one dummy run with size 0.

Merge 4 runs with size 0, 500, 800, and 1000 to produce a run with a run length of 2300. The new run length is calculated as follows $L_{mrg}=L_0+L_1+L_2+L_3=0+500+800+1000=2300$
Merge the run as made in step 1 with the remaining 3 runs bearing length 1000, 1200, 1500. The merged run length is 6000 and is calculated as follows

$L_{merged}=L_{mrg}+L_4+L_5+L_6=2300+1000+1200+1500=6000$

The resulting run has length 6000 records.

Part b

For step 1

Input Output Time

Input Output Time is given as

$T_{I.O}=\frac{L_{run}}{Size_{block}} \times Time_{I/O \, per\, block}$

Here

L_run is 2300 for step 01
Size_block is 100 as given
Time_{I/O per block} is 2 sec

$T_{I.O}=\frac{L_{run}}{Size_{block}} \times Time_{I/O \, per\, block}\\T_{I.O}=\frac{2300}{100} \times 2 sec\\T_{I.O}=46 sec$

So the input/output time is 46 seconds for step 01.

CPU Time

CPU Time is given as

$T_{CPU}=\frac{L_{run}}{Size_{block}} \times Time_{CPU \, per\, block}$

Here

L_run is 2300 for step 01
Size_block is 100 as given
Time_{CPU per block} is 1 sec

$T_{CPU}=\frac{L_{run}}{Size_{block}} \times Time_{CPU \, per\, block}\\T_{CPU}=\frac{2300}{100} \times 1 sec\\T_{CPU}=23 sec$

So the CPU time is 23 seconds for step 01.

Total time in step 01

$T_{step-01}=T_{I.O}+T_{CPU}\\T_{step-01}=46+23\\T_{step-01}=69 sec\\$

Total time in step 01 is 69 seconds.

For step 2

Input Output Time

Input Output Time is given as

$T_{I.O}=\frac{L_{run}}{Size_{block}} \times Time_{I/O \, per\, block}$

Here

L_run is 6000 for step 02
Size_block is 100 as given
Time_{I/O per block} is 2 sec

$T_{I.O}=\frac{L_{run}}{Size_{block}} \times Time_{I/O \, per\, block}\\T_{I.O}=\frac{6000}{100} \times 2 sec\\T_{I.O}=120 sec$

So the input/output time is 120 seconds for step 02.

CPU Time

CPU Time is given as

$T_{CPU}=\frac{L_{run}}{Size_{block}} \times Time_{CPU \, per\, block}$

Here

L_run is 6000 for step 02
Size_block is 100 as given
Time_{CPU per block} is 1 sec

$T_{CPU}=\frac{L_{run}}{Size_{block}} \times Time_{CPU \, per\, block}\\T_{CPU}=\frac{6000}{100} \times 1 sec\\T_{CPU}=60 sec$

So the CPU time is 60 seconds for step 02.

Total time in step 02

$T_{step-02}=T_{I.O}+T_{CPU}\\T_{step-02}=120+60\\T_{step-02}=180 sec\\$

Total time in step 02 is 180 seconds

Merging Time (Total)

Now the total time for merging is given as

$T_{merge}=T_{step-01}+T_{step-02}\\T_{merge}=69+180\\T_{merge}=249 sec\\$

Total time in merging is 249 seconds seconds

Why is weather forecast so important for hang gliders?

professor190 [17]

Well, it wouldn't be such a good idea if they got caught up in a storm, would it? :p

Strong winds could blow them off-course, or even lightning has a chance of striking the hand glider, causing damage to the glider, the person, or even both.

Additionally, a weather forecast can help in my generic situations. For example, knowing whether to wrap up warm for cold weather, or wear something a bit more loose and breathable for hot weather.
