The 6 steps for PowerPoint competency from the TED talk in the module "How to Avoid Death by PowerPoint."?

KIM [24]

Answer:

1. Do some presentation preparation work

2. Set the right tone and end on a high note.

3. Create sleek and stylish slides.

4. Get your audience to focus.

5. Its all about you.

Explanation:

1. Do some presentation preparation work:

A good presentation begins, not with slides, but with a pencil and paper. Research your audience’s background, interests and capabilities. What do they already know, for instance, and what can they learn from you?

2. Set the right tone and end on a high note:

You have no more than 30 seconds to secure your audience’s attention. So, what attention-grabbing opener will you use?

Visual communications expert Curtis Newbold suggests “a fascinating quote; an alarming or surprising statistic; asking your audience a question; telling a relevant and funny joke… an imaginary scenario; or a demonstration''.

3. Create sleek and stylish slides:

Once you have your story down, you can start to design your slides.

Before you do, it’s important to think about the practicalities. Will they, for instance, be displayed Widescreen with a 16:9 ratio? Or Standard with 4:3? This might seem like a small detail, but it can make a huge difference in terms of visual impact.

4. Get your audience to focus:

The most important thing is to grab your audience’s attention straight away – and then maintain it! You want your audience to go away having learned something. So, make it as easy as possible for people to grasp your message “from the off”!

5. Its all about you:

Finally, remember that, ultimately, it’s you that the audience should be paying attention to, not your slides!

PowerPoint can be used to create great visual aids, but the success of your presentation is determined by the way you deliver them. So, tell your story with a confident, compelling physical presence, and master it by rehearsing it 10 to 15 times.

Indicate if the following statements are True or False. Statement Circle one Internet Service Providers (ISPs) are proprietary n

Artyom0805 [142]

Answer:

False

Explanation:

Proprietary networks are those that are privately and exclusively managed, controlled and even owned by some organizations.

Internet Service Providers (ISPs) are companies that provide internet access services to companies and consumer products. They allow devices to connect to the internet. They offer much more than just internet access. They also offer related services such as email access, web development and virtual hosting.

ISPs can be open source or proprietary. They could be owned by a community, a firm and even non-profit organizations.

What would you have to know about the pivot columns in an augmented matrix in order to know that the linear system is consistent

Scrat [10]

Answer:

The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

$rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)$

Then satisfying this theorem the system is consistent and has one single solution.

Explanation:

1) To answer that, you should have to know The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

$rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)$

$rank(A)$

Then the system is consistent and has a unique solution.

$\left\{\begin{matrix}x-3y-2z=6 \\ 2x-4y-3z=8 \\ -3x+6y+8z=-5 \end{matrix}\right.$

2) Writing it as Linear system

$A=\begin{pmatrix}1 & -3 &-2 \\ 2& -4 &-3 \\ -3 &6 &8 \end{pmatrix}$ $B=\begin{pmatrix}6\\ 8\\ 5\end{pmatrix}$

$rank(A) =\left(\begin{matrix}7 & 0 & 0 \\0 & 7 & 0 \\0 & 0 & 7\end{matrix}\right)=3$

3) The Rank (A) is 3 found through Gauss elimination

$(A|B)=\begin{pmatrix}1 & -3 &-2 &6 \\ 2& -4 &-3 &8 \\ -3&6 &8 &-5 \end{pmatrix}$

$rank(A|B)=\left(\begin{matrix}1 & -3 & -2 \\0 & 2 & 1 \\0 & 0 & \frac{7}{2}\end{matrix}\right)=3$

4) The rank of (A|B) is also equal to 3, found through Gauss elimination:

So this linear system is consistent and has a unique solution.

Jose is upgrading the memory on his laptop. The laptop has two slots for RAM, but one of them is currently being occupied. He ha

inn [45]

Answer:

Reseat the new stick of RAM

Explanation:

Joe needs to reseat the new stick of the RAM. For that, he should gently release the clips which hold RAM in the correct posture, and one on each side. Joe is required to do this for each of the available memory modules. And then he will have the cautiously replace all the memory modules( 2 in number) through to DIMM slots which are on the motherboard. Make sure that you have noted down the locations of each notches on the RAM as well as the DIMM slots.
