What is the correct formula for the value of the determinant?
la bl
|c d|

Answers

Answer 1

Answer:

[tex]D = ab - cd[/tex]

Explanation:

Given

[tex]\left[\begin{array}{cc}a&b\\c&d\end{array}\right][/tex]

Required

Determine the determinant

Represent the determinant with D

Since the above matrices is 2 by 2.

All we have to do is to multiply the alternate elements of the columns

i.e. (a * d) and (b * c)

Then subtract:

[tex]D = (a * d) - (b * c)[/tex]

Simplify

[tex]D = (ad) - (bc)[/tex]

[tex]D = ab - cd[/tex]

My husband is a kid at heart so he absolutely loved spending an afternoon reminiscing with some of his favorite childhood games. There is no need to raid the piggy bank for quarters. A wristband ($13 per adult, $7 per child) allows you access to play unlimited games all day. You are welcome to come and go as you please so you can take breaks for lunch or to shop for soaps and sponges at the Sponge Docks.

My only complaint is that my husband insisted that we play all of the games as two players and he managed to crush my high scores on every game! Will definitely be returning to Replay Amusement Museum for a rematch soon!

Note to the parents: This is not an arcade that you can drop your children off at. All minors must be accompanied by an adult and anyone entering the building must pay for a wristband.

There are 12 teams in the Jayhook Hockey League.


Each team plays every other team twice per season, once at home and once away from home.

Last season 34 of the matches played resulted in a tie. Of the others, 18 more were won by the home

team than by the away team.




1: How many games did any one particular team play?


2: How many total games were played in the league?


3: What was the Won-Loss record by Home Teams last season?

Answers

Answer:

22 games

132 games

58 - 40

Explanation:

Given that:

Total Number of teams = 12

Number of times a team play every other = 2 (home and away)

Number of ties = 34

Let :

home wins = x

Away wins = x - 18

1: How many games did any one particular team play?

(Total Number of teams - 1) * number of times a team play every other

(12 - 1) * 2

11 * 2 = 22 games

2: How many total games were played in the league?

(Number of games played per team * number of teams) / 2

(22 * 12) / 2

= 264 /2

= 132 games

3: What was the Won-Loss record by Home Teams last season?

Total number of games = 132

Home wins + away wins + ties = 132

x + x - 18 + 34 = 132

2x + 16 = 132

2x = 132 - 16

2x = 116

x = 58

Home team wins = 58

Away team wins = home team loss = 58 - 18 = 40

Hence, Won - Loss record by Home team :

58 : 40

Punishment and reinforcement are often confused with each other, especially when the positive and negative are involved. Respond to parts 1 and 2 below. Define, as simply as you can, reinforcement and punishment. Explain how one might accomplish reinforcement and punishment through the use of positive reinforcement, negative reinforcement, positive punishment, and negative punishment. Include examples where appropriate.

Answers

Answer:

1. Reinforcement is when a reward is given or a bad stimulus is removed to make a specific behavior increase in frequency. A punishment is the addition of an unwanted event or the removal of a wanted stimulus in order to decrease a specific behavior.

2. Positive reinforcement is when a reward is added to increase a behavior, like giving a reward for returning a lost wallet. Negative reinforcement is when you remove an unwanted stimulus, like not nagging a child when they do their chores. Positive punishment is when you add an unwanted stimulus to stop the behavior, like spanking a child when they're bad. A negative punishment is when you remove a wanted stimulus, like taking away video games when the student hasn't done their homework..

Which of the following psychologists explained the development of conditioned emotional responses?

Garcia
Bandura
Pavlov
Skinner
Watson

Answers

Answer:

Watson :)

Explanation:

John Watson and Rosalie Rayner

John B. Watson explained the development of conditioned emotional responses. Therefore, option E) is correct.

What are conditioned emotional responses?

The term conditioned emotional response can be referred to specific learned behavior commonly used in classical or Pavlovian conditioning research. It can also be called "conditioned fear response (CFR)."

It can be described as an "emotional response" that results from classical conditioning, from the association of a neutral stimulus with a painful or fear-inducing unconditional stimulus. For example, if seeing a dog is paired with the pain of being bitten by the dog, seeing a dog can become a conditioned stimulus that elicits fear.

John B. Watson and Rayner demonstrated similar fear conditioning in the Little Albert experiment. B.F. Skinner and William Kaye Estes were the first to use this term and demonstrated the phenomenon with rats. They were trained food-deprived rats to lever-press for food pellets. Periodically, a tone was presented, for a small time, which co-terminated with an electric shock to the metal floor.

Answers

A - a curved surface cannot be represented on a flat surface without distortion

Every map projection has some degree of distortion because A a curved surface cannot be represented on a flat surface without distortion

How to explain the map projection

A curved surface cannot be represented on a flat surface without distortion. This is because a flat surface has only two dimensions, while a curved surface has three dimensions. When you try to project a three-dimensional object onto a two-dimensional surface, some of the information is lost and some of the features are distorted.

The other options are not correct. Parallels and meridians do cross at right angles on a globe, the grid system is two-dimensional, Earth is not a perfect sphere, and latitude lines are not shorter than meridian lines.

The correct option is A.

2. Explain what Gladwell means when he claims “you have to be intelligent enough” or “intelligence has a threshold” in relation to becoming an outlier.

Answers

Answer:

It means that an individual who believes to be an outlier has to be smart enough to have a perception of his position in the groups in which he lives, however this perception must be punctual and limited so as not to create problems and discomfort for himself.

Explanation:

This is because an outlier is an individual who is part of a group of other individuals, but who is different and does not fully fit the standard determined and observed by the members of that group. In this case, it is important that the outlier is smart enough to understand that it is different and that this group limits or harms him, so he can look for other groups that offer more advantages. However, this intelligence must be limited, as it is very difficult to establish a group that is fully adapted to the outlier and if that individual finds differences in any group that participates, he will be harmed, because he will live in complete isolation.
