Answer:
Following are the correct python code to this question:
n1 = float(input('Input first number: '))#input first number  
n2 = float(input('Input second number: '))#input second number  
n3 = float(input('Input third number: '))#input third number  
n4 = float(input('Input fourth number: '))#input fourth number  
average = (n1+n2+n3+n4)/4 #calculate input number average
product = n1*n2*n3*n4 # calculate input number product
print('product: {:.0f}  average: {:.0f}'.format(round(product),round(average))) #print product and average using round function
print('product: {:.3f}  average: {:.3f}'.format(product,average)) #print product and average value
Output:

Explanation:
The description of the above python code can be defined as follows:
- In the above python program four variable "n1, n2, n3, and n4" is defined, in which we take input from the user end, and in these user inputs we use the float method, that converts all the input value in to float value.
- In the next step, two variable average and product are defined, that calculate all input numbers product, average, and hold value in its variable.
- In the last line, the print method is used, which prints its variable value by using a round and format method.

HTML5
HTML5 has fewer plug-ins like the ability to standardize how audio and video are presented on a Web page. It introduces the <video> element designed to remove the need to install 3rd party add-ons and plug-ins like adobe flash player. It also adds the <audio> element  too that allows pages to smoothly add audio files.

Explanation:
The responsibility of the software architect is to ensure that all parts of the software system are able to meet the requirements set forth by the project or specifications, in this case, the technical standards.  This is an important piece of the software system because without it, the software system may not perform the necessary functions that it was written to do.
