Answer:

The solution code is written in Python

d = 1.5 + random.random() * 6

Explanation:

By presuming the Python random module is imported, we can use the <em>random</em> method to generate a random number.  <em>random.random()</em> will give us a value in the range [0, 1). The ensure the lower limit is 1.5 instead of 0, we can add 1.5 to random.random()

  •      1.5 + random.random()

This expression will give any value in range [1.5, 2.5)

To ensure the upper limit is set to 7.5, we tweak the previous expression to

  • 1.5 + random.random() * 6  

This expression will always multiply a random number from [0,1) with 6 and then only added with 1.5. This will always produce a random number that fulfill the inequality 1.5 ≤ d < 7.5

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:

Please find the attachment.

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.
