Letter To The President

Assalamualaikum Warrahmatullahi Wabarakaatu,

Shalawat and salam to our beloved Prophet Muhammad PBUH, his family and his companions. With honour and all due respect my name is Ataa Martin and this letter is my opinion on things that you should do when you become the president.

The president of Indonesia should basically support the people when they need it the most, without help the Indonesian civilization is in danger with corruption and also public destruction. My opinions about this is that the government should help more instead of putting money into their pockets, this will also be a bad image to other countries making them know that Indonesia is one of the top corruption and low technology countries with no available skills to different countries. Look at the people that are walking around and look at the facilities that are given by the government, basically it’s all filthy and disgusting for tourists that are visiting the country. Also about our orphanages, technically it’s low on budget and this basically must be fixed. It will also affect the children and might even lead them to work on the streets and making them not successful in life and the after due to the sins they commit because of no education. Indonesia has basically plenty of religious Islamic places but instead of developing them, they rather build public malls and other useless places that we already have. You must try with every power you have to show the people what’s right in life and the after, instead of encouraging them to spend much money on useless things.

Well this is basically the end of my letter and contribution, sorry if I have made some mistakes and I’m hoping that you will fix the country to make it a better place.

Wassalmu’ alaikum Warrahmartullahi Wabarakaatu

Sincerely, Ataa Martin

Chapter 11

Chapter 11: Percentages

11.1 Using mental methods:

In this chapter you will be learning more about percentages, some percentages are really easy to find because they are simple fractions. While others are difficult because the fractions are really hard to find.

Worked Example 11.1: These percentages are all easy to find

There are 4600 people in a stadium. 58% are males. How many is that?

100% = 4600                   

58% = 50% + 10% - 2%

50% = 2300

10% = 460

1% = 46

Question (Small Test):

19% of 256 = 48.64

Use this fact to find the question above:

      

        A.     19% of 128 B. 9.5% of 256 C. 19% of 512 D. 9.5 of 512

11.2 Comparing different quantities

You will often need to compare groups that are different sizes. Suppose that, in one school, 85 students took an exam and 59 passed. In another school, 237 students took an exam and 147 passed. Which school did better? It is hard to say because each school had a different number of students.

Worked Example 11.2: Which school had a better pass rate?

59 out of 85 = 59 ÷ 85 = 69%

147 out of 237 = 147 ÷ 237 = 62%

The pass rate in school B is better by seven percentage points

Computer Network:

A computer network or data network is a telecommunications network that allows computers to exchange data. In computer networks, networked computing devices pass data to each other along data connections. The connections (network links) between nodes are established using either cable media or wireless media. The best-known computer network is the Internet.

Network computer devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as servers and personal computers, as well as networking hardware. Two devices are said to be networked when a device is able to exchange information with another device.

Computer networks support applications such as access to the World Wide Web, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications. Computer networks differ in the physical media used to transmit their signals, the communications protocols to organize network traffic, the network's size, topology and organizational intent.

Wired Technologies:

Twisted pair wire is the most widely used medium for all telecommunication. Twisted-pair cabling consist of copper wires that are twisted into pairs. Ordinary telephone wires consist of two insulated copper wires twisted into pairs. Computer network cabling (wired Ethernet as defined by IEEE 802.3) consists of 4 pairs of copper cabling that can be utilized for both voice and data transmission. The use of two wires twisted together helps to reduce cross talk and electromagnetic induction. The transmission speed ranges from 2 million bits per second to 10 billion bits per second. 

Math: Unit 10 (10.1 & 10.2)

Calculating Statistics:

You can use statistics to summarise sets of Data. You can also use them to compare different sets of data. You should already be able to calculate three different averages that include the following: the Mode, the Median and the Mean. The range isn't average, It basically measures how to spread out a set of values or numbers. The large set of data, it isn't practical to list every number apart. Instead, you can record the data in a frequency table.

Mode: Is the most common value or number
Median: Is the middle value, when they are listed in order
Mean: Is the sum of all the values divided by the number of values
Range: Is the largest value minus the smallest

(Worked Example 10.1)
[Find the mode, mean and range]

Number of beads: (25 30 35 40 45 50)
Frequency: (34 48 61 30 15 12)

The mode 35 --> The mode is the number with the highest frequency.
6900/200 = 34.5 --> (25 x 34 + 30 x 48 + 35 x 61 + 40 x 30 +45 x 15 + 50 x 12)
50 - 25 = 25 --> This is the difference between the largest and smallest number of beads

10.2 (using statistics)

In heal situation, you need to decide which one to use. To measure how spread out a set of measurements is, the range is the most useful statistic. To find a representative measurement, you need an average. Should it be the mode, the median or the mean. It all depends on the particular situation.\

Short Summary:

• Choose the mode if you want to know which is the most commonly occurring number.
• The median is the middle value, when the data value are put in order. Half the numbers are greater than the median and half the numbers are less than the median.
• The mean depends on every value. If you change one number you change the mean.

(Worked example 10.2)

[here are the ages, in years, of the players in a football team. Work out the average age. Give a reason for your choice of average]
