Four students measured the mass of a piece of metal whose accurate mass is 34.75g. Their results are 34.2g, 33.75g, 35.0g, and 34.69g. Explain whether the results are precise or accurate​

Answers

Answer 1

Answer:

The given data are more precise than they are accurate

Explanation:

From the given measurements, we have;

The accurate mass = 34.75 g

The deviations from the accurate measurement is as follows;

34.2 g - 34.75 g = -0.55 g

33.75 g - 34.75 g = -1 g

35.0 g - 34.75 g = 0.25 g

34.69 g - 34.75 g = -0.06 g

For precision measurement, we find the average deviations as follows;

The sum of the deviations = -0.55 g - 1 g + 0.25 g - 0.06 g = -1.36 g

The average deviation = -1.36 g/4 = -0.34 g

For accuracy measurement, we find the average of the absolute deviations as follows;

The sum of the absolute deviations = 0.55 g + 1 g + 0.25 g + 0.06 g = 1.86 grams

The average absolute deviation = 1.86 g/4 = 0.465 g

Therefore, the magnitude of the average deviation is less than the magnitude of the absolute deviations, therefore, the given data are more precise than they are accurate

James wants to create a web page where he can write two paragraphs of text. The first paragraph of text should be colored red and the
second blue. Which snippet of code show the principle behind how James creates this page?

Answers

Answer:

The first code does it

Explanation:

Each of the attached code snippet is divide into two parts.

The CSS partThe html part

From the four code snippets, the first one answers it.

The syntax to format the paragraph of an html text using css is:

p#paragraph-id{

color:color-name

}

Analysing each element

p# -> This implies that a paragraph is to be formatted

paragraph-id -> This represents the id of the paragraph

{} -> The open and close curly braces house the properties to be formatted

color:color-name -> implies that the color of the element be changed to color-name (e.g. red or blue)

In the body tag of the html code, the first paragraph has an id of para1 and the second has para2 as its id.

i.e. <p id = "para1">......

So, the first paragraph will be formatted red while the second will be blue

Imagine you're in charge of managing an annual fest at your school. You have to select students and assign them different tasks. Write a short essay on the qualities and traits you would be looking for while selecting students. Explain why you think these qualities and traits are important. Also, describe how the lack of such qualities and traits would affect the work.

Answers

Answer:

Quality traits are important in many ways. A persons traits identifies them of how they treat you or how you might treat them. It is important to find good working people for the job. For example if one student is good at a specific task I might put them in that task or if another is good at stocking shelves or finding books I might put them in the library to help students find books. It is important as a supervisor to find people that listen and follow instructions not people that mess around and are unorganized. These qualities and traits are important to see the real potential of the employees. Finding the right people for the job will help the school and you as the supervisor to manage these employees. Making a application or employment sheet will help to find the right people making a sheet with some questions and have the potential employees fill it out to find their traits and skills.

Major innovations made from the establishment of abucus to the 5th computer generation

Answers

Answer:

Cogs and Calculators

It is a measure of the brilliance of the abacus, invented in the Middle East circa 500 BC, that it remained the fastest form of calculator until the middle of the 17th century. Then, in 1642, aged only 18, French scientist and philosopher Blaise Pascal (1623–1666) invented the first practical mechanical calculator, the Pascaline, to help his tax-collector father do his sums. The machine had a series of interlocking cogs (gear wheels with teeth around their outer edges) that could add and subtract decimal numbers. Several decades later, in 1671, German mathematician and philosopher Gottfried Wilhelm Leibniz (1646–1716) came up with a similar but more advanced machine. Instead of using cogs, it had a "stepped drum" (a cylinder with teeth of increasing length around its edge), an innovation that survived in mechanical calculators for 300 hundred years. The Leibniz machine could do much more than Pascal's: as well as adding and subtracting, it could multiply, divide, and work out square roots. Another pioneering feature was the first memory store or "register."

Apart from developing one of the world's earliest mechanical calculators, Leibniz is remembered for another important contribution to computing: he was the man who invented binary code, a way of representing any decimal number using only the two digits zero and one. Although Leibniz made no use of binary in his own calculator, it set others thinking. In 1854, a little over a century after Leibniz had died, Englishman George Boole (1815–1864) used the idea to invent a new branch of mathematics called Boolean algebra. [1] In modern computers, binary code and Boolean algebra allow computers to make simple decisions by comparing long strings of zeros and ones. But, in the 19th century, these ideas were still far ahead of their time. It would take another 50–100 years for mathematicians and computer scientists to figure out how to use them (find out more in our articles about calculators and logic gates).

ASCII is a common format for the representation of characters in writing code. How many characters can be represented in the standard ASCII encoding

Answers

Answer:

A total of 128 characters can be represented in the standard ASCII encoding.

Explanation:

The American Standard Code for Information Interchange (ASCII) was created to make an international standard for encoding the Latin letters. In 1963, ASCII was received so data could be deciphered between PCs; speaking to lower and upper letters, numbers, images, and a few orders.

Since ASCII is encoded using ones and zeros, the base 2 number framework, it uses seven bits. Seven bits permits 2 to the power of 7 = 128 potential blends of digits to encode a character.

ASCII consequently ensured that 128 significant characters could be encoded.
