names = ['Peter', 'Bruce', 'Steve', 'Tony', 'Natasha', 'Clint', 'Wanda', 'Hope', 'Danny', 'Carol']

numbers = [100, 50, 10, 1, 2, 7, 11, 17, 53, -8, -4, -9, -72, -64, -80]

for index, element in enumerate(names):

if index % 2 == 0:

print(element)

for num in numbers:

if num >= 0:

print(num, end = " ")

count = 0

for i in numbers:

count += i

avg = count/len(numbers)

print("sum = ", count)

print("average = ", avg)

for num in numbers:

if num % 2 != 0:

print(num, end = " ")

A group of statisticians at a local college has asked you to create a set of functions that compute the median and mode of a set

Vanyuwa [196]

Answer:

from functools import reduce

def mean(mylist):

score = reduce(lambda x,y: x + y, mylist)/ len(mylist)

return score

def median(mylist):

sorted(mylist)

list_len = len(mylist) % 2

i = round(len(mylist)/2)

x = len(mylist)//2

if list_len == 0:

median = (mylist[x] + mylist[x+1]) / 2

else:

median = mylist[i]

return median

def mode(mylist):

unique = set(mylist)

unique = list(unique)

collector = [mylist.count(key) for key in unique]

maxi = max(collector)

loc = collector.index(maxi)

return unique[loc]

def main():

scores = input( 'Enter list of numbers: ').split(",")

scores = [int(score) for score in scores]

operation = input('Enter operation: ')

operator = ['mean', 'median', 'mode']

for x in iter(list, 0):

if operation in operator:

break

print("Invalid operation: ")

operation = input('Enter operation')

index_loc = operator.index(operation)

if index_loc == 0:

return mean(scores)

elif index_loc == 1:

return median(scores)

#return np.median(scores) can be used of the defined function

elif index_loc == 2:

#return stats.mode(scores)[0] can be used of the defined function

return mode(scores)

print( main( ) )

Explanation:

The main python function calls conditionally three statistical functions namely mean, median and mode. It prompts for user input for a list of integer numbers and a function name name to return the corresponding result.

C++

Ede4ka [16]

Answer:

2 & 3

Explanation:

Only mathematical operations that can be used to change contents of pointer variables include addition, subtraction, comparison, increments and decrements.

Although modulus, division and multiplications are not possible. A snippet of code is attached showing pointers addition and subtraction and their result.

Check it by replacing + or - signs with *, / or % which represent multiplication, division and modulus respectively. It would result in an error.

Draw an E-R diagram for the following situation:

VladimirAG [237]

Answer:

Hi there! This question is good to check your knowledge of entities and their relationships. The diagram and explanation are provided below.

Explanation:

The entity relationship diagram for the association between the entities according to the description in the question is drawn in the first attachment. We can further simplify the relationship by removing this many to many relationship between "Chemists" and "Projects" by adding another entity called "Worklist" as detailed in second attachment.
