Vocabulary - Chapter 6 - Variation and Formulas
Relationship: In mathematics a relationship is a connection between two variables; changing the value or one of the variables changes the value of the other
Variable: Lette or symbol used to represent a quantity that can change
Variation: A relationship between two variables, which can be expressed as a formula, a table of values, or as a graph
Direct Variation: The relationship between two variables x and y with the form y=kx where k is a constant. A direct variation may be represented by a straight line graph which passes through the origin (0,0)
Constant of Variation: The value of k in the direct variation formula y=kx. K is equal to the slope of the line when the variation is graphed
Directly Proportional: Means the same as varies directly
Y varies directly as x: Gives the formula y=kx for variation constant, k
Fixed Cost: A cost that remains constant
Partial Variation: The relationship between two variables x and y with the form y=kx + F where k is the constant of variation and F is a fixed number. A partial variation may be represented by a straight line graph with slope k and which passes through the point (0,F)
Variable Cost: A cost that changes depending upon the amount of goods puchased
Vertical Intercept: The value where a graph touches or crosses the vertical axis
Direct Squared Variation: A relationship between two variables which can be written in the form y=kx squared where k is the constant. The shape of a graph showing this variation will be curved. The curve will begin at the origin
Varies directly as the square: Y varies directly as the square of x gives the formula y=kx squared with the constant of variation, k.
Inverese Variation: A relationship between two variables which can be written in the form y= k divided by x where k is a constant. A graph showing this variation decreases as you move to the right along the horizontal axis

Chaper 8- Vocabulary
Percentile rank: Indicates the percentage of scores less than or equal to a particular score; is the proportion of scores in a distribution that a specific score is greater than or equal to
Normal curve: A graph resembling a bell-shaped curve
Histogram: A graph that displays the frequency of data
Normal distribution: The frequency distribution of the normal curve
Correlation coefficient: The relationship between two sets of data
Negative correlation: As one variable increases the other decreases, or as one variable decreases the other increases
Positice correlation: As one variable increases so does the other, or as one variable decreases so does the other
R-value: Correlation coefficient
Zero Correlation: The variables have nothing to do with each other, so there is no relation between the two sets of data

Vocabulary- Chapter 4
Capital gain: Money earned in an equity investment
Capital loss: Money lost in an equity investment
Debt investment: An investment that involves lending money to a company
Equity investnent: An investment that involves part ownership in a company
Canada Deposit Insurance Corporation: A corporation that offers protection for certain investments in Canadian financial institutions
Face value: Value at the maturity date
Maturity date: The date on which you can redeem your GIC, bond, or T-bill without penalty
Term: Length of an investment
The Rule of 72: To quickly estimate the length of time it takes for an investment to double in value, divide 72 by the interest rate (as a number, not a percentage) to find the time in years. For example, if the interest is 10%, divide 72 by 10. It would take 7.2 years.
