A company noticed a recent spike in online posting about one of their products. In response, they increased the amount of paid advertising for that particular product. However, sales of the product dropped by 65% in the next 4 months. Which big data value component was missing from the analysis about the spike?

Answers

Answer 1

Answer:

missing big data value component from the analysis about the spike could be causality

Explanation:

It appears that the missing big data value component from the analysis about the spike could be causality.
The company noticed a spike in online posting about the product, and in response, they increased the amount of paid advertising for that particular product.
However, this increased advertising did not lead to an increase in sales, but instead, sales dropped by 65%.
This suggests that there may be other factors at play beyond just the spike in online posting that the company was not aware of, and that may have contributed to the decrease in sales.
In order to fully understand the situation, the company should conduct further analysis to understand the cause of the spike in online posting and whether or not there is a causal relationship between that spike and the decrease in sales.

Hi, I'm working on "How many Names" in CodeHS(python) right now and am stuck on some code. Is there anything I need to add or change or remove?

Here are the directions:

Some people have just a first name and a last name. Some people also have a middle name. Some people have five middle names.

Write a program that asks the user how many names they have. (If they have a first name, two middle names, and a last name, for example, they would type 4.) Then, using a for loop, ask the user for each of their names. Store the names in a list.

Then, use slices to separately print the person’s first name, middle name(s), and last name.

My Code is this:

fullname = " "
names = int(input("how many names do you have: "))
for i in range (names):
cheese = input("what is your name: ")
fullname = fullname +" "+ cheese
print ("First name:" + str(cheese))
print ("Middle names:" + str(cheese))
print ("Last name:" + str(cheese))

Answers

Your code correctly prompts the user for the number of names they have and then uses a for loop to collect their names and store them in the variable "fullname". However, you will have to do some adjustments to print each of the user's names as their first name, middle name(s), and last name.

One way to do this is to store each name as an element in a list and then use list slicing to access the first, middle, and last elements. Here's an example of how you can modify your code to achieve this:

names = int(input("how many names do you have: "))

name_list = []

for i in range (names):

cheese = input("what is your name: ")

name_list.append(cheese)

print("First name: " + name_list[0])

print("Middle names: " + " ".join(name_list[1:-1]))

print("Last name: " + name_list[-1])

In this example, the input names are stored in a list called name_list. By using list slicing and the join() method you can print each part of the name separately.

write a program to determine whether a number n is equal to the sum of its proper positive divisors excluding the number itself

Answers

PROGRAM

Here is a program in Python that determines whether a number n is equal to the sum of its proper positive divisors (excluding the number itself):

def is_perfect(n):

divisors = []

for i in range(1, n):

if n % i == 0:

divisors.append(i)

if sum(divisors) == n:

return True

else:

return False

n = int(input("Enter a number: "))

if is_perfect(n):

print(n, "is a perfect number.")

else:

print(n, "is not a perfect number.")

The function is_perfect(n) takes an integer n as input, and uses a for loop to find all the positive divisors of n, excluding n itself. It then checks if the sum of these divisors is equal to n. If it is, the function returns True, indicating that n is a perfect number. If the sum of the divisors is not equal to n, the function returns False, indicating that n is not a perfect number.

The program prompts the user to enter a number, then calls the is_perfect(n) function to check if the number is a perfect number. If it is, the program prints that the number is a perfect number, otherwise it prints that the number is not a perfect number.

It's important to note that there are not many perfect numbers, and for larger numbers this algorithm could become inefficient. In case you need to work with large numbers, it is more efficient to use the Sieve of Eratosthenes algorithm to generate the perfect numbers.

What is Karen's holding period return assuming that the current offer price is $8.50 and the NAV is $8.20? a) 2590 b) 32% c) 36% d) 40% How do you think human creative expression can affect issues we deal with today? Be specific about the issues you are addressing. Use the insights you gained from studying artifacts to explain how creative expression can impact todays issues A nucleus with binding energy Eb1 fuses with one having binding energy Eb2. The resulting nucleus has a binding energy Eb3. What is the total energy released in this fusion reaction? O -(Eb1 + Eb2 + E63) (1 + Eb2) - OE1 + Eb2+ OE - 1 - Eb2 A new project will require an initial investment of $250,000. Using the companys required rate of return of 13 percent, the project's NPV is $900. Should the project be accepted? Why or why not?Yes; It will earn an annual return of 13 percent.Yes; It will earn $900.Yes; It will earn an annual return of 13 percent, plus an additional $900 in present value dollars.No; It will earn only $900.No; It will earn a return of only .4 percent. Explore what happens if we add, subtract or multiply triangular matrices? Do we get a Triangular matrix or something else? Create a 5 by 5 matrix by typing: U = round( 10 * rand(5) Similarly create 5 by 5 matrices B and C by typing V= round( 10 * rand(5)) W= round( 10 * rand(5)) Type: L tril (U) to create a lower triangular matrix from U. Type: K-tril(V) to create another lower triangular matrix from V. Type: J triu(V) to create an upper triangular matrix from V. Now find the following: L-K3L+5K (Note: you need to type 3*L+5*K)LK . KL K^3J+K5JJ^2Answer the following questions: a.) Explain: What type of matrix are you getting? Is it lower triangular , upper triangular, or other type that you know? b.) Is it possible that "the sum of two lower triangular matrices be non-lower triangular matrix"? Explain. c.) What do you think about "the product of scalar( number) with a lower triangular matrices should it be a lower triangular matrix"? Why? Explain d.) What do you think about dividing a lower triangular matrix by a lower triangular matrix will the result be a lower triangular matrix? Explain e.) Generalize your findings and extend them to sum, difference, product, and scalar product of upper triangula matrices.For example 1. Sum of two upper triangula matrices is......... why did president franklin d. roosevelt withhold support for the league of nations' condemnation of japanese and german aggression in 1933?
