Print preview allows you to view the layout of your paper before you print it hence the pre part of preview.
What is Print preview?A feature called print preview shows what a printed copy would look like on the screen. By checking the layout using print preview before printing, you can detect any potential problems and prevent the need for multiple prints, saving ink or toner and paper.
You can examine a page in landscape mode by switching the page orientation in the print preview from portrait to landscape. Sadly, not all software supports this function.
You are unable to see how your page will print in landscape format if the program you are using lacks any settings or print preview features.
Therefore, Print preview allows you to view the layout of your paper before you print it hence the pre part of preview.

For a processor with primary and secondary caches, an instruction cache miss rate of 1%, a data cache miss rate of 5%, a instruction mix of 40% data accesses, a primary to secondary cache miss penalty of 10 cycles and a secondary cache to main memory miss penalty of 200 cycles and a secondary miss rate of 0.2%, what will be the contribution to total CPI from the cache misses (in decimal)
Answer:
The answer is "0.306".
Explanation:
The Primary to Secondary Memory Instruction miss cycle
[tex]= I \times 0.01 \times 10 = 0.1 I[/tex]
Data miss cycles[tex]= I \times 0.05 \times 10 \times 0.40 = 0.2 I[/tex]
The Secondary to main Memory Instruction miss cycle[tex]= I \times 0.01 \times 200 \times 0.0002 = 0.004 I[/tex]

If the system has a mechanical advantage of 5 and the load of 350N.What effort is needed to lift the weight? Provide your answer in newtons
Answer:
Effort = 70 N
Explanation:
A machine is a device that can be used to overcome a load by the application of a minimal effort. For a practical machine, mechanical advantage (MA) is the ratio of the load (L) overcome to the effort (E) applied.
i.e MA = [tex]\frac{Load}{Effort}[/tex]
In the given question, MA = 5 and the load = 350 N. So that;
5 = [tex]\frac{350}{E}[/tex]
E = [tex]\frac{350}{5}[/tex]
= 70
The effort applied to the machine is 70 N.

Roger wants to give semantic meaning to the contact information, which is at the bottom of the web page. To do this he will use a footer element as a ______ of the contact information.
Answer:
Parent
Explanation:
HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.
Generally, all HTML documents are divided into two (2) main parts; body and head. The head contains information such as version of HTML, title of a page, metadata, link to custom favicons and CSS etc. The body of a HTML document contains the contents or informations that a web page displays.
In this scenario, Roger wants to give semantic meaning (an element conveying informations about the type of content contained within an opening and closing tag) to a contact information placed at the bottom of a webpage. Thus, in order to do this, he should use a footer element as a parent of the contact information and as such all instance variables that have been used or declared in the footer class (superclass) would be present in its contact information (subclass object).

Answer:
(a): power(2&-2)
The code is as follows:
power = 2**-2
print(power)
(b): Largest and smallest in a list
The code is as follows:
num = [33,6,11,100,456,109,-4,366]
smallest= min(num)
largest= max(num)
print(smallest)
print(largest)
(c): Loop in Python
(i) Loop are instructions that are repeated until a certain condition is met;
(ii) For loop, in python are used to iterate over a sequence or through a certain range;
The syntax is:
for loop_element in range(iterating_range):
The following is an illustration of for loop that iterates 5 times
for i in range(5):
Explanation:
(a): power(2&-2)
The ** is used to calculate power.
So, 2**-2 represents 2 raise to power -2
power = 2**-2
This prints the calculated power
print(power)
(b): Largest and smallest in a list
This initializes the list
num = [33,6,11,100,456,109,-4,366]
This calculates the smallest using min() function
smallest= min(num)
This calculates the largest using max() function
largest= max(num)
This prints the smallest and the largest
print(smallest)
print(largest)
(c): See answer section
