Critical Thinking

#35
Biconditional:
- A statement is a biconditional statement if and only if it is a statement that can be written in the form "p if and only if q."

Conditional: 
- If a statement is a biconditional statement, then it is a statement that can be written in the form "p if and only if q." (True)

Converse: 
- If a statement can be written in the form "p if an only if q", then it is a biconditional statement. (True)

The biconditional is true because both the conditional statement and converse are true.


Write About It

Definition: 
- A ray that divides an angle into two congruent parts.

Conditional:
- If a ray divides an angle into two congruent parts, then it is an angle bisector.

Converse: 
- If a ray is an angle bisector, then it divides an angle into two congruent angles.

The saying "A good definition is reversible" means that the meaning is good if both the conditional and statement are true. Like for example, the angle bisector. Both its conditional and converse are true, so that means the word was defined well.


Short Response

#41
Bicondtional: 
-You will get a traffic ticket if and only if you are speeding.

Conditional Statements:
- If you get a traffic ticket, then you are speeding.
- If you are speeding, then you will get a traffic ticket.

Biconditional is false because the conditional of the biconditional is false. In order for the biconditional to be true, both the converse and conditional have to be true.

Redesigning Cereal Box

          Hi guys, my name is Shana Mafnas. I am currently attending Mount Carmel School on the island of Saipan. I love food, sleep, and singing even if I'm not very good at it. This blog is mostly about how I redesigned my box.

          The packages and the products inside seem odd. If you open the box and look at the amount of cereal the package holds, the cereal fits about 1/2 or more of the box (depending on which cereal you buy). It is a waste of space. If the company has to spend more money on the box, they should minimize the size of the box, right? If they choose to minimize it then they spend less money.

          Do I consider these packages environmentally friendly? Yes, I guess. Unless the box bursts into flames and the air gets polluted. If that has ever happened then they should change the box that the cereal comes in. In other matters, the box doesn't cause any harm.

          In order to reduce the excess packaging I think they should minimize the size of the plastic inside the box. In the plastic, the cereal will most likely fill up half. They should minimize it and in order to keep it fresh, they should vacuum seal the plastic so that the cereal doesn't get spoiled. After, they minimize the box as well to go with the mass of the package inside. That way, it would be more handy and it doesn't take up as much space as it used to.

         The shelf storage and visual appeal are affected by the design of the box. How is the question. Well, if the box is big it will give the customers the thought of the amount of the cereal inside to be big as well as the box. That is how they get the customers to buy their product. It also takes up a lot of space on the shelves. Some stores will order more shelves but maybe the rate of shelves bought by stores will lower if the box is designed as smaller box. It will take up less storage on the shelves.

Volume means the amount of space an object takes up. So, the surface area of the box really depends on the volume of the cereal. If the amount of cereal is 10x more than the original amount of cereal, the box will be 10x bigger as well. So the surface area is affected by the volume of the cereal that is inside it.

          Redesigning a cereal box took many tries for me. When I did finish the project, I had to redo it in school because I did it wrong. It actually ended up being a fun project. It taught me that some things should consume as much space as they already do.  

Here are my computations and picture of the box after the project.
