Matrices
A matrix with 3 rows and 4 columns is said to have this order.
What is 3 times 4?
In a network diagram, a line that connects two vertices (or nodes) is known by this term.
What is an edge?
In the recurrence relation V0 = 1000, Vn+1 = Vn + 50, the value $50$ represents this type of interest earned per compounding period.
What is simple interest?
Data that represents measurable quantities, such as height, weight, or temperature, is classified as this broad type of data
What is numerical data?
This special square matrix has 1s on the leading diagonal (from top-left to bottom-right) and 0s everywhere else.
What is the identity matrix?
For a connected graph to contain an Eulerian trail but NOT an Eulerian circuit, it must have exactly this many vertices with an odd degree.
What is two?
This form of depreciation reduces the value of an asset by a fixed percentage of its current value each year, rather than a flat amount.
What is reducing balance depreciation?
In a boxplot, this measure of spread is calculated by subtracting the first quartile (Q1) from the third quartile (Q3).
What is the Interquartile Range (IQR)?
For the matrix product AB to be mathematically defined, the number of columns in Matrix A must equal this property of Matrix B.
What is the number of rows?
This step-by-step algorithm is used to solve assignment and allocation problems by operating on a bipartite graph matrix.
What is the Hungarian algorithm?
This interest rate metric reflects the actual annual interest paid or earned on a loan when compounding occurs more frequently than once a year.
What is the effective interest rate?
In the least squares line equation y = a + bx, the variable $b$ represents this property of the line.
What is the slope (or gradient)?
A square matrix does not have an inverse if this specific calculated value is exactly zero.
What is the determinant?
This tree connects all the vertices of a weighted graph without forming any loops, resulting in the lowest possible total edge weight.
What is a minimum spanning tree?
A financial investment where regular, equal payments are withdrawn from an account over time until the balance reaches zero is known as this.
What is an annuity?
This time-series smoothing technique replaces each data point with the mean of itself and a set number of adjacent points to remove random variation.
What is moving average smoothing?
In a regular Markov chain represented by a transition matrix, the state matrix will eventually reach this stable state where it no longer changes from step to step.
What is the steady state (or long-term equilibrium)?
In critical path analysis, an activity has this property if its earliest starting time (EST) is exactly equal to its latest starting time (LST).
What is zero float (or a float of zero)?
In this specific type of financial arrangement, the regular withdrawal amount is exactly equal to the interest earned per period, leaving the principal balance unchanged indefinitely.
What is a perpetuity?
This statistical value, symbolised by r^2, tells us.
What is the percentage of variation in the response variable that is explained by the variation in the explanatory variable.
