Verse of the Week

11For I know the plans I have for you,” declares the LORD, “plans to prosper you and not to harm you, plans to give you hope and a future. 12Then you will call upon me and come and pray to me, and I will listen to you. 13You will seek me and find me when you seek me with all your heart. 14I will be found by you,” declares the LORD.

Jeremiah 29:11-14a

Key Concepts – Second Semester

 

q  Chapter 6 Review – Mathematical Curves

o   Conic Sections: Circle, Ellipse, Parabola, Hyperbola

o   Sine Curve: Amplitude, Wavelength, Frequency

o   Spirals: Archimedean (arithmetic sequence), Logarithmic (geometric sequence)

 

q  Chapter 7 Review – Methods of Counting

o   Fundamental Counting Principle (multiply ways each event can occur)

o   Factorial – n! = multiply consecutive numbers from n down to 1

o   Permutations – arrangement in a definite order – P(n,r) = n!/(n-r)!

o   Combinations – selection where order doesn’t matter – C(n,r) = P(n,r)/r!

 

q  Chapter 8 Review – Mathematics of Chance

o   Probability: the measure of chance of an event happening from equally likely possible outcomes

§  calculated: (# ways event can occur)/(# of possible outcomes)

§  measured: (# times event occurred)/t# of possible outcomes)

§  expressed as a fraction or decimal from 0 to 1, or as a percentage from 0% to 100%

o   Successive Events: multiply the probabilities of the individual events

§  dependent or independent

o   Binomial: two possible outcomes

o   Pascal’s Triangle: helps determine binomial probabilities

o   Complementary Events: where an event occurs, and an event doesn’t occur

§  sum of these two probabilities always adds up to 1

 

q  Chapter 9 Review – An Introduction to Statistics

o   Frequency Distributions

o   Measures of Central Tendency: Mean, Median, Mode

o   Measures of Variability: Range, Standard Deviation, Normal Curve

o   Sample, Population
