Write a class named Episode. An instance of this episode class will represent a single episode of a TV show, with a title, a season number, and an episode number. For example "Friends, season 1, episode 1", or "The Wire, season 3, episode 5." Your class should have the following constructors and methods: A constructor that accepts three arguments: a String for the title, an int for the season number, and an int for the episode number. A constructor that accepts only a String, for the title, and sets the season and episode numbers to 1. A setter and getter for the title. (never mind the season and episode numbers.) A method named "equals", that accepts an Episode, and returns true if the title, season number and episode number are the same as the receiving object's. A method named "comesBefore". This method should also accept an Episode. It should return true if the episode that receives the invocation comes before the parameter. That is only true if the two objects have the same title, and if the argument comes from a later season, or the same season, but a later episode. Write only the class. Do not write a whole program

The advantages of automation include: (I) reduced output variability. (II) reduced variable costs. (III) machines don't strike or file grievances. (IV) machines are always less expensive than human labor.

Answers

Answer:

(III) machines don't strike or file grievances.

(IV) machines are always less expensive than human labor.

Explanation:

The advantage of automation among the option is:

(III) machines don't strike or file grievances - Machine has the advantage of not going on strike or filing grievances. It just obey instruction. Strike are human way of showing grievances. With automation, there is no issue of strike or filing for grievance.

(IV) machines are always less expensive than human labor - Machines as a means of automation are very cheap when compared to human labor. The only added cost for machine is the added cost after the cost of purchase. For human labor, the cost is not fixed or predictable.

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

Answers

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.

Similar background and text

Answers

Answer: Dark background and light text.

Explanation:

Assuming when you mean by "light text", you mean by white text. This should be able to be readable by users visiting the site.

Answer:

Contrasting background and text

Explanation:

When selecting a color scheme for a website, designers often choose complementary colors that keep the visitor on the website.

Your web page should have three main colors: one for the background, one for the text, and one for the headings. The colors you select should complement each other and be on opposite sides of the color wheel.
