Q1 QUESTION 1 OF 71
A tree is
CORRECT ANSWER
any graph that is connected and has no circuits.
RATIONALE
A tree is defined as a connected graph without cycles, ensuring a single path between any two nodes.
This acyclic and connected property distinguishes it from other graph structures.
Q2 QUESTION 2 OF 71
Linear
CORRECT ANSWER
means something is increasing by a fixed amount or decreasing by a fixed amount (straight line)
RATIONALE
A linear relationship signifies a constant rate of change, meaning the dependent variable changes by
a fixed increment for each unit increase in the independent variable, graphically represented by a
straight line. This concept is central to understanding proportional relationships and basic algebraic
functions.

The bottom number in a fraction.
Page 2
, RATIONALE
The denominator represents the total number of equal parts into which a whole is divided. It signifies
the divisor in a fractional expression, indicating the quantity by which the numerator is to be divided.
Q4 QUESTION 4 OF 71
Normal distribution Problems
CORRECT ANSWER
Always draw a bell curve label mean and shade the region you want to find the percent
RATIONALE
Visualizing the normal distribution with a bell curve, clearly marking the mean and shaded area,
facilitates accurate calculation of probabilities or percentages within specific ranges. This graphical
representation reinforces the understanding of standard deviations and their impact on the
distribution's shape and area.
Q5 QUESTION 5 OF 71
GPA
CORRECT ANSWER
Multiply each numeric grade by the number of credits the course was worth.
Add together
Divide this result by the number of credit hours taken
Round to two decimal points
RATIONALE
Calculating a GPA requires weighting each course's grade by its credit hours to reflect its
contribution to the academic performance, then averaging these weighted grades. This process
ensures that courses with more credit hours have a greater impact on the final GPA calculation.
