CONVERTING MEASUREMENTS, ESTIMATES AND CONVERSIONS =)

hey there?!

Last Tuesday and Wednesday we talk about the estimates and conversions.
We also talk about a technique to be easy to know the conversion.
For example:

• KING = KILO
• HENRY = HECTO
• DIED = DECO
• MOTHER/ LADY/ GRANDMOTHER = METER/ LITER/ GRAMS
• DIDN'T = DECI
• CARE = CENTI
• MUCH = MILI

Mr. K also mentioned the word MNEMONIC. Mnemonic means is relating to, assisting, or intended to assist the memory. A device, such as a formula or rhyme, used as an aid in remembering.we also do some exercises for example:

convert 500mm to feet: 500mm x0.03937= 19.7 inches, and there are 12 inches in a foot , so 19.7/12=1.64 feet ( or 1 foot and 7.7 inches).

how did i get the 86500. the first thing i do is i look at the king Henry died mother didn't care much the MNEMONIC. I move the decimal point to the right to get the 86500. if you dont get it just used the mnemonic to see how many zero your going to put.It always has a smiley faces. The most important thing that we should remember is the conversions of the imperial and the metric measurements. do you know that the imperial and the metric system are different. The imperial is complicated than the metric. The main difference between metric an imperial (American) system of measurements is that the metric system is a breeze to use, and all the scientific measurements are given in metric. Since it's a system based on 10, every measurement is divisble by 10, in terms of scaling up and down. In other words, a yardstick is divided by 36 inches. A meterstick (about 39 inches) is divided into 100 parts. So, if you need to convert centimeters to meters, you just multiply by 100. (Instead of yards to feet, or feet to inches)

This are the conversions of imperial and metric:

Imperial/USA unit	Metric (SI) unit		Metric (SI) unit	Imperial/USA unit
Ounce (weight)	28.35 grams		Gram	0.035 ounces
Pound	0.45 kilograms		Kilogram	2.21 pounds
UK ton (2240 pounds)	1.02 metric tons		Metric ton (1000 kg.)	0.98 UK tons
US ton (2000 pounds)	0.91 metric tons		Metric ton (1000 kg.)	1.10 US tons

Imperial/USA unit	Metric (SI) unit		Metric (SI) unit	Imperial/USA unit
Inch	2.54 centimeters		Centimeter	0.39 inches
Foot	30.48 centimeters		Meter	3.28 feet
Yard	0.91 meters		Meter	1.09 yards
Mile	1.61 kilometers		Kilometer	0.62 miles

Earlier beginning of the class we talked about digital ethics which is you don't have to post any pictures ourselves because we being so careful to our own privacy and we can only use our first name and if you really wantedto have your own graphic association image with your posting . you may also used avatar. a something represent you but its NOT you..

Later on, we also talk about the y-intercept and what is the meaning of it be by using graphic calculator. This are the steps how to used the graphic calculator by solving the y-intercept:

• When we used the graphic calculator we press STAT and look for the EDIT and list they points.You should enter the data in the list. To get to the list (1) one or list (2) two. To clear the list press the up and down button, clear and enter your data.
• when your going to create a scatter plot you should press 2nd function, y=, and enter. Choose scatter plot, x list and y list.
• if your going to graph the the plot, your going to press ZOOM 9. first, you should adjust your WINDOW.
• To create a regression equation. Press STAT, ARROW to the LEFT and move to the CALC and pick your regression and then press 2nd function (1)one, comma, 2nd function (2) two and comma.
  

• Press VARS, arrow to the right and move to the Y-vars ENTER to the function and ENTER.

This are the types of regression:
- linear
- quadratic
- exponential
- sinusoidal
- logarithmic
- power

we also correct our quiz in the end of our class. we talk about the y-intercept and also how to write the equation of the line. do you know the meaning of interpolations? Interpolations means is to estimate values of(data or a function) between known values.

This are the things that i learned in our class today. My scribes not too short but in this post you can easily understand by is step.

The next scribe will be THUAN. (^_^)
