NCSSM PLACEMENT TEST WITH COMPLETE
SOLUTIONS 100% 2023/2024
binomial
a polynomial with two terms
constant
a value that does not change
factor
a number or expression that is multiplied by another number or expression to get a product
monomial
a number or a product of numbers and variables with whole-number exponents, or a polynomial with
one term
polynomial
a monomial or a sum or difference of monomials
consistent system
a system of equations or inequalities that has at least one solution
dependent system
a system of equations that has infinitely many solutions
elimination method
a method used to solve systems of equations in which one variable is eliminated by adding or
subtracting two equations of the system
inconsistent system
a system of equations or inequalities that has no solution
independent system
a system of equations that has exactly one solution
substitution method
A method used to solve systems of equations by solving an equation for one variable and substituting
the resulting expression into the other equation(s)
system of linear equations
a system of equations in which all of the equations are linear
correlation
a measure of the strength an direction of the relationship between two variables or data sets
, correlation coefficient
a number r greater than or equal to -1 and less than or equal to 1, that describes how closely the
points in a scatter plot cluster around the line of best fit.
linear regression
a statistical method used to fit a linear model to a given data set
residual
the signed vertical distance between a data point and a line of fit
X-Intercept
The x-coordinate(s) of the point(s) where a graph intersects the x-axis.
Y-Intercept
The y-coordinate(s) of the point(s) where a graph intersects the y-axis.
Linear Function
A function that can be written in the form y=mx+b, where x is the independent variable and m and b
are real numbers. Its graph is a line.
Rate
A ratio that compares two quantities measured in different units.
Rate of Change
A ratio that compares the amount of change in a dependent variable to the amount of change in an
independent variable.
Slope
A measure of the steepness of a line.
Exponent
The number that indicates how many times the base in a power is used as a factor.
Exponential Expressions
An algebraic expression in which the variable is in an exponent with a fixed number as the base.
Exponential Function
A function in the form f(x)=ab^x where a and b are real numbers, a does not equal zero, b>0, and b
does not equal 1.
Perfect Square
A number whose positive square root is a whole number.
