which of the following statements about rfid is not true? rfids require line-of-sight contact to be read. rfids transmit only over a short range. rfids use an antenna to transmit data. microchips embedded in rfids are used to store data. rfids can track individual units within a shipment.

Answers

Answer 1

The statement "RFIDs require line-of-sight contact to be read" is not true. RFIDs do not require line-of-sight contact to be read, which is contrary to the other statements that are true about RFIDs.

RFID (Radio Frequency Identification) technology is commonly used for identification, tracking, and data transmission purposes. It consists of tags or labels that contain a microchip and an antenna. These tags can be attached to objects or products, enabling them to be identified and tracked wirelessly.

Contrary to the statement, RFIDs do not require line-of-sight contact to be read. Unlike traditional barcodes, which need to be scanned directly, RFIDs can be read without a direct line of sight. The radio waves used in RFID technology can penetrate materials such as plastic, cardboard, and even some metals. This allows for convenient and efficient reading of RFIDs, even when they are enclosed or hidden within objects or packaging.

RFIDs typically transmit data over a short range, usually within a few meters. The exact range may vary depending on the specific RFID system and the operating frequency used. However, advancements in RFID technology have led to the development of long-range and even passive RFID systems capable of greater transmission distances.

2. Write a program code using if...else if...else statement asking the user to enter an option between "Fiction" or "Nonfiction" books using upper case function. Accept number of copies from the user. Calculate and display the total price based on the following table Note: Total Price = Rate per book X No of copies


fiction 50
non fiction 30
other invalid​

Answers

Answer:

option = input("Enter 'Fiction' or 'Nonfiction' book: ").upper()

copies = int(input("Enter number of copies: "))

if option == "FICTION":

   rate_per_book = 50

   total_price = rate_per_book * copies

   print("Total price for " + str(copies) + " copies of fiction book: " + str(total_price))

elif option == "NONFICTION":

   rate_per_book = 30

   total_price = rate_per_book * copies

   print("Total price for " + str(copies) + " copies of nonfiction book: " + str(total_price))

else:

   print("Invalid option")

This code uses an if...elif...else statement to check the user's input for the option of "Fiction" or "Nonfiction" books. The input is converted to upper case using the upper() function to ensure that the user's input is not case-sensitive. The number of copies is accepted from the user as an integer, and the total price is calculated based on the rate per book and the number of copies. The total price is then displayed. If the user enters an invalid option, the code will print "Invalid option".

Answers

Explanation:

The population standard deviation is always larger than the standard error when the sample size is greater than one (n > 1) because the population standard deviation reflects the variability of the entire population, while the standard error reflects the variability of a sample. As the sample size increases, the variability of the sample will become closer to that of the population as whole, and so the population standard deviation will be greater than the standard error.

which statements compares the copy and cut commands

Answers

The statement that accurately compares the copy and cut commands is 2)Only the cut command removes the text from the original document.

When using the copy command, the selected text is duplicated or copied to a temporary storage area called the clipboard.

This allows the user to paste the copied text elsewhere, such as in a different location within the same document or in a separate document altogether.

However, the original text remains in its original place.

The copy command does not remove or delete the text from the original document; it merely creates a duplicate that can be pasted elsewhere.

On the other hand, the cut command not only copies the selected text to the clipboard but also removes it from the original document.

This means that when the cut command is executed, the selected text is deleted or "cut" from its original location.

The user can then paste the cut text in a different place, effectively moving it from its original location to a new location.

The cut command is useful when you want to relocate or remove a section of text entirely from one part of a document to another.

T/F : Both character literals and string literals can be assigned to a char variable.

Answers

True. Both character literals and string literals can be assigned to a char variable.

In programming languages like C, C++, and Java, character literals are single characters enclosed in single quotes (''). String literals, on the other hand, are sequences of characters enclosed in double quotes (""). While character literals represent individual characters, string literals represent a sequence of characters.

A char variable can store a single character, so it can be assigned a character literal directly. For example, you can assign the character 'A' to a char variable like this: char c = 'A';. The variable c will hold the value 'A'.

Similarly, a char variable can also store a string literal, but only if the string has a length of one character (i.e., a single character string). In this case, the variable will hold the first character of the string. For example, you can assign the string literal "Hello" to a char variable like this: char c = "Hello";. However, the variable c will only store the character 'H', and the rest of the string will be truncated.

In summary, both character literals and string literals can be assigned to a char variable, but a char variable can only store a single character, so string literals longer than one character will be truncated.

You carried out a PERT analysis of a very large activity-event network using only slightly skewed or symmetric beta distribution models for the activity durations. Your analysis yields a mean duration of 56.2 time units for the critical path with a variance of 3.4. What is your best estimate of the probability of successful project completion in 57 time units or less? Provide your answer as a number between 0 and 1 with 3 decimals (3 digits after the decimal point, for example: 0.123).

Answers

PERT (Program Evaluation and Review Technique) is a network analysis technique commonly used in project management.

It is particularly useful when there is a high level of uncertainty surrounding the duration of individual project activities. PERT uses probabilistic time estimates, which are duration estimates based on using optimistic, most likely, and pessimistic estimates of activity durations, or a three-point estimate.

These estimates help to identify the likelihood of meeting project deadlines and can assist project managers in developing effective project schedules and resource allocation plans. Overall, PERT is an important tool for managing complex projects with uncertain activity durations.
