QUESTIONS WITH ANSWERS
DRADE A (2025/26)
An intravenous drip is infused at a rate of 4.5 milliliters per minute. How many
milliliters are infused per hour?
A. .075mL
B. 2.7mL
C. 75mL
D. 270mL
- CORRECT-ANSWERSD. 270mL
Base Number
- CORRECT-ANSWERS The number multiplied by itself when paired with an
exponent. For example, in 8 to the third power (8^3), 8 would be the base number.
Trailing Zeros
- CORRECT-ANSWERS Sequence of zeros after the last non-zero digit in a decimal
number.
Equation
- CORRECT-ANSWERS Two Mathematical expressions separated by the equals sign,
=. The two expressions on either side of the equals sign hold the same value as
one another.
Bar Chart
- CORRECT-ANSWERS A graph that displays data that is distributed over groups or
categories.
Relative Frequency
- CORRECT-ANSWERS A way to approximate a percentage by dividing the number of
times an event occurred in an experiment by the total number of trials.
Causal Relationship
, - CORRECT-ANSWERS A relationship between two variables that can be classified
as cause-and-effect.
Random Experiment
- CORRECT-ANSWERS Experiment in which the outcome is not known ahead of time
and in which results do not affect future outcomes.
A patient's medication was increased by 40 milligrams. What is the percent
increase in the medication if the original medication was 180 milligrams?
A. 2.2%
B. 4.5%
C. 22.2%
D. 45%
- CORRECT-ANSWERS C. 22.2%
Factorization
- CORRECT-ANSWERS The process of determining the prime factors of a composite
number.
Unit Multiplier
- CORRECT-ANSWERS A fraction that contains two equivalent quantities but in two
different units, used in order to convert units.
Division Principle of Equality
- CORRECT-ANSWERS If both sides of the equation are divided by the same non-
zero number, the result is an equivalent equation.
Symmetry
- CORRECT-ANSWERS The quality of the data having the same shape on both sides
of the mean.
Contingency Table
- CORRECT-ANSWERS A table that contains frequency counts for two categorical
variables. Also see Two-Way Frequency Table.
Correlation
- CORRECT-ANSWERS An observed relationship between two quantitative
variables. While this is most commonly a linear relationship, it does not need to
