Assume that source elements of length k are mapped in some uniform fashion into a target elements of length p. If each digit can
lukranit [14]

Answer And explanation

a)

r^k has 1/r^k probability guess the correct source

b)

Each element in r^p  is mapped by r^k / r^p . There are r^k^-^p  So there are  r^k^-^p -1 elements.

number of target elements = r^k^-^p

number of source elements = r^k^-^p -1

probability = r^k^-^p -1 /r^k

c) Probability of the correct target element

1/r^p

A company wants to use online methods to target more customers. It decides to conduct a market research by collecting the data o
Ronch [10]

Answer:

They could use a CRM

A CRM tool lets you store customer and prospect contact information, identify sales opportunities, record service issues, and manage marketing campaigns, all in one central location — and make information about every customer interaction available to anyone at your company who might need it.

They Could Use PDC

The term “primary data” refers to data you collect yourself, rather than data you gather after another party initially recorded it. Primary data is information obtained directly from the source. You will be the first party to use this exact set of data.

They Could Use Quantitative vs. Qualitative Data

Quantitative data comes in the form of numbers, quantities and values. It describes things in concrete and easily measurable terms. Examples include the number of customers who bought a given product, the rating a customer gave a product out of five stars and the amount of time a visitor spent on your website.

Why Should I Track Users Data:

To ensure it's going smoothly, it's important to keep track of data that directly correlates to the potential success of your business. Key performance and financial metrics can help you address any problems with your business before they occur

This program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balance
aleksandr82 [10.1K]

Answer:

Question Options :

(1) Prompt the user to input five pairs of numbers: A player’s jersey number (0 – 99) and the player’s rating (1 – 9). Store the jersey numbers in one int array and the ratings in another int array. Output these array(i.e., output the roster).

(2) Implement a menu of options for a user to modify the roster. Each option is represented by a single character. The program initially outputs the menu, and outputs the menu after a user chooses an option. The program ends when the user chooses the option to Quit. For this step, the other options do nothing. (2 pt)

(3) Implement the “Output roster” menu option. (1 pt)

(4) Implement the “Add player” menu option. Prompt the user for a new player’s jersey number and rating. Append the values to the two arrays. (1 pt)

(5) Implement the “Delete player” menu option. Prompt the user for a player’s jersey number. Remove the player from the roster (delete the jersey number and rating). (2 pts)

(6) Implement the “Update player rating” menu option. Prompt the user for a player’s jersey number. Prompt again for a new rating for the player, and then change that player’s rating. (1 pt)

(7) Implement the “Output players above a rating” menu option. Prompt the user for a rating. Print the jersey number and rating for all players with ratings above the entered value. (2 pts)
