How many bits would be needed to count all of the students in class today? There are 5 children in the class.

Answers

Answer 1

Answer:

To represent the 5 children as a computer bit, we make use of the equation $2^b = n$ . 3 bits are required to represent the 5 children.

Given that

$n = 5$ ---- number of children

The number of bits (b) is calculated as:

$2^b = n$

Substitute 5 for n

$2^b = 5$

Take logarithm of both sides

$\log(2)^b = \log(5)$

Apply law of logarithm

$b * \log(2) = \log(5)$

Make b the subject

$b = (\log(5))/(\log(2))$

$b = 2.32$

The number of bits must be an integer. So, we use the greatest integer closest to 2.32. The integer is 3

So:

$b=3$

Hence, the number of bits to represent the 5 children is 3.

IN PYTHON Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, and output all integers less than or equal to that value. Ex: If the input is: Enter the number of integers in your list: 5 Enter the 5 integers: 50 60 140 200 75 Enter the threshold value: 100 the output is: The integers that are less than or equal to 100 are: 50 60 75The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75. Such functionality is common on sites like Amazon, where a user can filter results. Your code must define and call the following two functions: def get_user_values() def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold) Utilizing functions will help to make your main very clean and intuitive.

This quiz is meant to test your understanding of secure passwords. Click on the title and answer the following questions in the submission box: What are the characteristics of a secure password? Why is phishing harmful?

Given the following: int funcOne(int n) { n *= 2; return n; } int funcTwo(int &n) { n *= 10; return n; } What will the following code output? int n = 30; n = funcOne(funcTwo(n)); cout << "num1 = " << n << endl; Group of answer choices Error num1 = 60 num 1 = 30 num1 = 600 num1 = 300

Answers

Answer:

num1 = 600

Explanation:

Given

The attached code snippet

Required

The output of n = funcOne(funcTwo(n)); when n = 30

The inner function is first executed, i.e.

funcTwo(n)

When n = 30, we have:

funcTwo(30)

This returns the product of n and 10 i.e. 30 * 10 = 300

So:

funcTwo(30) = 300

n = funcOne(funcTwo(n)); becomes: n = funcOne(300);

This passes 300 to funcOne; So, we have:

n = funcOne(300);

This returns the product of n and 2 i.e. 300 * 2 = 600

Hence, the output is 600
