Answer:
import random
randomlist = []
for i in range(0,20):
n = random.randint(-29,30)
if n < 0 :
n = 100
randomlist.append(n)
print(randomlist)
Explanation:
The random module is first imported as it takes care of random. Number generation.
An empty list called randomliay is created to hold the generated random integers.
Using a for loop, we specify the range of random numbers we want.
Inside the for loop ; we attach our generated random integer which will be in the range (-29 to 30) in a variable n
For each n value generated, if the value is less than 0( it is negative, since all the values are integers), replace the value with 100.
Answer:
RANK.AVG
Explanation:
Required
Arrange data in descending order based on average
The feature to do this is to use the RANK.AVG() function.
By default, the function will return the ranks of the selected data in descending order (i.e. from highest to lowest); though, the sort order can be changed to ascending order.
The syntax is:
=RANK.AVG (number, ref, [order])
Where
number 
The number to use as rank
ref The cell range
order 0 represents descending order while 1 represents ascending order
