FC: A YEAR IN REVIEW | Survey Of Mathematics | Julie Dawn Turner
1: Chapter !1 Thinking Skills | Magic Squares | Middle number= middle square 1st & last numbers = right & left hand Next two go on diagonal
2: "Math classes are like fudge ... mostly sweet with a few nuts." | Chapter 8: The Metric System | Kilometer (km) Hectometer (hm) Dekameter (dkm) M, L, G Decimeter (dm) Centimeter (cm) Millimeter (mm) | Up - Left Down - Right
3: Chapter 2: Sets | 200 people were surveyed. 12 people said they scored high on writing. 8 people said they scored high on Math. 18 People said they scored hight on Reading. 8 people said they scored high on both writing and reading. 8 people said they scored high on Math and writing. 11 people said they scored high on writing and math. 22 People said they score high on all three.
4: Chapter 3: Logic
5: Chapter 4: Systems of Numeration | Change of base.... 453(base 6) = ____(base 10) 4(36) + 5(6) + 3(1) 144 + 30 +3 177 453 (base 6) = 177 (base 10) | ... , 7776, 1296, 216, 36, 6, 1 4 5 3 | Converting a base 6 to a base 10.
6: Chapter 11: Consumer Mathematics | SOLD
7: SOLD | House Project
8: Chapter 12: Probability | Four Important Facts: 1. The probability of an event than cannot occur is 0. 2. The probability of an event must occur is 1. 3. Every probability is a number between 0 and 1 inclusive; that is 0 < P(E) < 1 4. The sum of probability of all possible outcomes is an experiment is 1.
9: Statistics Skeleton 1. Order the data from least to greatest 2. High = H Low = L 3.Range = R=H-L 4. Number of classes (given) 5. Width= R / # of classes Round to the next whole number if a decimal. 6. Mean - Average (round to the nearest 10th) 7. Median - Middle number or numbers 8. Mode - the number that occurs most often. (might be 1 or more than one) 9. Midrange - (H+L) / 2 10. Write the first data item, add the width to get the next number. Add the width continuously until you reach the number of classes. Subtract 1 from the second number on the left to get the first number on the right, Add the width continuously until you reach the number of classes. 11. Frequency - count the numbers within each class, total at the bottom. 12. Cumulative frequency - Copy first frequency number, add the first frequency number to the second frequency number to get the second cumulative frequency number, Continue this process until you reach the number of data items. 13. Standard deviation Data (Data - Mean) (Data - Mean)(squared) Total all Total / n - 1 = Variance Square root of variance = Standard Deviation (round 4 places to the right.) 14. Quartiles: Q1 = use use blue snake to come to the middle (below Q2). Q2 = Median (should already be determined in step 7 Q3= Use blue snake to come to the middle (above Q2). 14.
