To practice a presentation with Presenter View, but without access to an additional monitor, what shortcut can be used?

Oxnard Casualty wants to ensure that their e-mail server has 99.98 percent reliability. They will use several independent server

sattari [20]

Answer:

The smallest number of servers required is 3 servers

Explanation:

Given

$Reliability = 99.98\%$

$Individual Servers = 95\%$

Required

Minimum number of servers needed

Let p represent the probability that a server is reliable and the probability that it wont be reliable be represented with q

Such that

$p = 95\%\\$

It should be noted that probabilities always add up to 1;

So,

$p + q = 1$ '

Subtract p from both sides

$p - p + q = 1 - p$

$q = 1 - p$

Substitute $p = 95\%\\$

$q = 1 - 95\%$

Convert % to fraction

$q = 1 - \frac{95}{100}$

Convert fraction to decimal

$q = 1 - 0.95$

$q = 0.05$

------------------------------------------------------------------------------------------------

To get an expression for one server

The probabilities of 1 servers having 99.98% reliability is as follows;

$p = 99.98\%$

Recall that probabilities always add up to 1;

So,

$p + q = 1$

Subtract q from both sides

$p + q - q = 1 - q$

$p = 1 - q$

So,

$p = 1 - q = 99.98\%$

$1 - q = 99.98\%$

Let the number of servers be represented with n

The above expression becomes

$1 - q^n = 99.98\%$

Convert percent to fraction

$1 - q^n = \frac{9998}{10000}$

Convert fraction to decimal

$1 - q^n = 0.9998$

Add $q^n$ to both sides

$1 - q^n + q^n= 0.9998 + q^n$

$1 = 0.9998 + q^n$

Subtract 0.9998 from both sides

$1 - 0.9998 = 0.9998 - 0.9998 + q^n$

$1 - 0.9998 = q^n$

$0.0002 = q^n$

Recall that $q = 0.05$

So, the expression becomes

$0.0002 = 0.05^n$

Take Log of both sides

$Log(0.0002) = Log(0.05^n)$

From laws of logarithm $Loga^b = bLoga$

So,

$Log(0.0002) = Log(0.05^n)$ becomes

$Log(0.0002) = nLog(0.05)$

Divide both sides by $Log0.05$

$\frac{Log(0.0002)}{Log(0.05)} = \frac{nLog(0.05)}{Log(0.05)}$

$\frac{Log(0.0002)}{Log(0.05)} = n$

$n = \frac{Log(0.0002)}{Log(0.05)}$

$n = \frac{-3.69897000434}{-1.30102999566}$

$n = 2.84310893421$

$n = 3 (Approximated)$

Hence, the smallest number of servers required is 3 servers

**NEED HELP??!! Computer Science Questions!! KNOWING GIMP!!!!

Svetlanka [38]

1. If my memory serves me well, the answer is true. Free select tool is also called lasso and it’s used to free-hand selection. You can also combine free select tool segments with polygonal segments or other shapes.

2. I think this statement is definitely “False”. As I’ve mentioned before you can combine free selection with other selection features like polygonal by using anchors.

3. I’m not 100% sure, but I guess this one is true. As far as I remember, add to selection mode lets you to add new selection to any existing areas. So I think it’s possible to add selection to the existing one.

4. I think this one is also true. But it allows you just paint it, but it’s also kinda modification. Quick Mask allows you to isolate subject and paint selected object. It helps you not to brush subject accidentally. It’s a very useful tool as for me.

5. Yes, this statement is 100% true. But it could be gray for GIMP, because the mask is coded in gray tones, but I think that black is also gray tone. Color black or gray removes part of selection, and color white adds area to existing selection.

6. According to what I’ve mentioned before this one is also true, so there’s no need for additional explanation.

7. Another tool, similar to the Lasso/Free Select tool is the B) Scissors Tool. As there was mentioned intelligent scissors tool is almost the same as lasso but more user-friendly.

8. It’s false. You must click to the first point of your selection to finish the process or you will lose your selection.

9. I think this one is true. Paths tool includes two or more line segments connected by handle points. These points are kinda anchors I guess.

10. After making a selection using the Paths Tool, I must select the the D) Selection from Path button to turn my path into a selection. You can find it in path tool options.

11. Yes, it’s true, it allows you to make complex selections with curved or straight lines. Just drag one of the anchors to curve the line. Also you can create different geometrical figures with this tool.

12. Yes this is true. But there are much more cool blur filters than only Gaussian blur. Experiment on your own.

13. You can do all of the following given above. Every layer is kinda isolated image and you can modify it however you want.

14. I’m definitely sure that this statement is true. Just find layer drop down menu and follow the instructions given in this question. It’s simple.

How do you select a single cell, a single column, a single

Vedmedyk [2.9K]

Answer:

To select nonsequential cells, click the first cell, hold down the Ctrl key, and click each additional cell (or row or column) you want to select. To selectthe entire worksheet, click the small box located to the left of column A and above row 1. Optionally, you can selectall cells in a worksheet by pressing COMMAND+A......

To select all cells on a worksheet, use one of the following methods:

Click the Select All button.Press COMMAND+A. Note If the worksheet contains data, and the active cell is above or to the right of the data, pressing COMMAND+A selects the current region. Pressing COMMAND+A a second time selects the entire worksheet.
