FC: A SEMESTER IN REVIEW | Survey of Mathematics | Khrystian Warren

1: The Metric System | K= kilo= 1000 x base unit H= hecto= 100 x base unit DA= deck= 10 x base unit BASE UNIT d= deci= 0.1 x base unit c= centi= 0.01 x base unit m= milli= 0.001 x base unit | 1 m = 1 yd 1 kg= 2.2 lb 1 l= 1qt | 0 degrees C = 32 degrees F (water freezes) 22 degrees C= 71.6 degrees F (room temperature) 37 degrees C= 98.6 degrees F (body temperature) 100 degrees C= 212 degrees F *F=(9/5)C+32 *C=(5/9)F-32 | 1 cm^3= 1mL= 1g 1dm^3= 1L= 1kg 1m^3= 1kL= 1 T (1T= 1000 kg) | 1 foot = 12 inches 1 yard= 3 feet 1 mile= 5280 feet 1 pound= 16 ounces 1 ton= 2,000 pounds 1 cup= 8 fluid ounces 1 pint= 2 cups 1 quart= 2 pints 1 gallon= 4 quarts 1 minute= 60 seconds 1 hour= 60 minutes 1 day= 24 hours 1 year= 365 days

2: Perimeter | The sum of the lengths of the sides of the figure | Perimeter of a Rectangle: P= 2L + 2w | Perimeter of a Square: P= 4s | Perimeter of a Parallelogram: P= 2b+2w | Perimeter of a Triangle: P= S1 + S2 + S3 *S3= base | Perimeter of a trapezoid: P= S1 +S2 + B1 + B2

3: Circles | A circle is a set of equal points equidistant from a fixed point called the center. | the radius (r) of a circle is a line segment from the center of a circle to any point on the circle | the diameter (d) of a circle is a line segment through the center of a circle with both end points on the circle. | the circumference is the length of the simple closed curve that forms a circle. | C=2*pi*r | A=pi*r^2

4: Estimation | The process of arriving at an approximate answer to a question | 19 - 20 x \$3.99 -x \$4.00 \$80.00 | 58,289.60 / 22.1 = 60,000 / 20 = 3,000

5: { | { | Area | A | Area of a Rectangle: A = l x w | Area of a Parallelogram: A = b x h | Area of a Trapezoid: A=(1/2)h(b1+b2) | Area of a triangle: A= (1/2)bh | Area of a Square: A=s^2 | (A) Region within the boundaries of the figure.

6: The sum of the lengths of the legs of the right triangle equals the square of the length of the hypotenuse. | Pythagorean Theorem | leg^2 + leg^2 = hypotenuse^2 | Symbolically, if a and b represent the lengths of the legs and c represents the length of the hypotenuse | a^2 + b^2= c^2

7: Stem and Leaf Displays | A stem and leaf display is a tool that organizes and groups the data while allowing us to see the actual values that make up the data | the stems are placed on the left hand side of the diagram, they are the unit number. | The leaves are placed on the right of the diagram, they are the remaining digits in a whole number.

8: Percent | a ratio of some number to 100. | 1. Divide the numerator by the denominator to obtain a decimal. 2. Multiply the decimal number by 100. 3. add a percent sign *changing a faction to a a percent | 1.Multiply the decimal by 100. 2.add a percent sign. *changing a decimal to a percent | 1.divide the number by 100. 2. remove the percent sign. *Changing a percent to a decimal | Percent change= (amount in latest period)- (amount in previous period) divided by the amount in the previous period and times 100.

9: Central Tendency | Mean- the sum of the data divided by the number of pieces of data. | Median- value in the middle of ranked data. Ranked data is data ordered from least to greatest. | Mode- piece of data that occurs most frequent. *sounds like "most" | Midrange- the lowest value added to the highest value divided by two. | Quartiles- divide data into four equal parts. | Determining quartiles: 1. list data from smallest to largest. 2.determine median. if there are two medians it will be in between the two. 3. the first quartile is the median of the lower half of data 4. the third quartile is the median of the higher half of data.

10: Each memory we keep with care means future happiness to share. | Thank you for all the silly memories! This has been a fun semester! :)
