In Web design, What kind of tag is referred to as fixed ?<br>

Tpy6a [65]

Answer:

Most HTML tags are fixed

Explanation:

There are various kind of technology one can use for designing web application. A web designer should know HTML, CSS and other basic building block of web development.

HTML meaning hypertext markup language is used to define the basic structure of a web page . HTML has tags which are used to declare the contents on the web page. The tags includes anchor(<a>), paragraph tag(<p>),header tag(<h1>).

CSS which is known as Cascading style sheet describes the presentation of the web pages.

Other tags in HTML includes <img>, <link>, <ul> etc and generally this tags are HTML tags which are fixed for a particular kind of job . For example you can't use an image tag <img> to enclose video instead you use a video tag <video> tag. The header tag <h1> cannot be represented like a paragrapgh tag<p> on the web page. The both of them serve specific purpose and are fixed.

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

<em />

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

$q = 1 - 0.95$

$q = 0.05$

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

<em>To get an expression for one server</em>

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 $Log0.05$

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

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

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

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

$n = 2.84310893421$

$n = 3 (Approximated)$

<em>Hence, the smallest number of servers required is 3 servers</em>

Write a Java program that prompts the user to enter integer values for the sides of a triangle and then displays the values and

satela [25.4K]

Answer:

import java.util.Scanner;

public class triangle {

public static void main (String [] args) {

int sideOne, sideTwo, sideThree;

Scanner in = new Scanner (System.in);

System.out.println("Enter the first side of the triangle");

sideOne = in.nextInt();

System.out.println("Enter the secon side of the triangle");

sideTwo = in.nextInt();

System.out.println("Enter the third side of the triangle");

sideThree = in.nextInt();

if ( sideOne<=0||sideTwo<=0|| sideThree<=0){

System.out.println(" The Values enter are "+sideOne+ "," +sideThree+ ","+sideThree+ " These values don't make a valid triangle");

}

else if ((sideOne + sideTwo> sideThree) || (sideOne+sideThree > sideTwo) || (sideThree+sideTwo > sideOne))

{

System.out.println ("The triangle is Valid");

}

else {

System.out.println(" The Values enter are "+sideOne+ "," +sideTwo+ ","+sideThree+ " These values don't make a valid triangle");

}

Explanation:

for a Triangle to be Valid one of the three sides of the triangle must greater than the other two sides. The code above enforces this condition using an if statement in combination with the Or Operator

The following conditions where enforced

side one, side two and side three != 0

Side One + Side Three > Side Two

Side Three + Side Two> Side One

Side Two + Side One > Side Three

Match the organelles to their functions.

noname [10]

Answer:

I. Smooth endoplasmic reticulum.

II. Golgi apparatus.

III. Lysosomes.

IV. Nucleus.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.

Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include;

1. Nucleus : it controls all the activities taking place in the cell and the synthesis of proteins. Thus, it's the organelle that commands other organelles.

2. Mitochondria : it provides all the energy required in the cell by transforming energy forms.

3. Lysosomes : they are responsible for absorbing materials and breaking the materials taken in by the cells. Thus, it digests foreign material.

4. Chromosomes : they give sets of instructions for the synthesis of products.

5. Ribosomes : they are involved in the build up of proteins.

6. Smooth Endoplasmic Reticulum : this is where the ribosomes perform their tasks. Thus, it produces lipids and fats.

7. Cytoskeleton : they help to maintain and support the shape of the cells.

8. Vesicles : they ensure proteins are properly transported to the right and exact location.

9. Golgi apparatus : it prepares the protein for export by chemically tagging them. Also, this organelle produces lysosomes.

10. Cell membrane : is the wall of the cell and typically controls what leaves and enters the cell.
