NES 103 Math Study Guide Questions with Correct
Solutions
pictograph
A picture or drawing representing words or ideas
circle graph
A graph of data where the entire circle represents the whole or 100%
Scatterplot
a graphed cluster of dots, each of which represents the values of two variables
correlation
A measure of the extent to which two factors vary together, and thus of how well either factor
predicts the other.
stem and leaf plot
A method of graphing a collection of numbers by placing the "stem" digits (or initial digits) in
one column and the "leaf" digits (or remaining digits) out to the right.
histogram
A graph of vertical bars representing the frequency distribution of a set of data.
Inference
A conclusion reached on the basis of evidence and reasoning
trend line
,a line on a scatter plot drawn near the points. it shows a correlation
Integers numbers
a number that cannot be expresed as a fraction a/b where a and b are integers and b does not
equal 0.
concrete examples
the use of real or tangible concepts used in a sentence to clarify understanding
symbolic representation
converting data to symbols
deductive reasoning
reasoning in which a conclusion is reached by stating a general principle and then applying that
principle to a specific case (The sun rises every morning; therefore, the sun will rise on Tuesday
morning.)
inductive reasoning
A type of logic in which generalizations are based on a large number of specific observations.
Adaptive Reasoning
capacity for logical thought, reflection, explanation, and justification
inverse
If not p, then not q
converse
, If q, then p
a guitar costs $120 plus 7% sales tax. How much are the tax and bill?
7%= 0.07
0.07 x 120 = $8.40 sales tax
$120 + $8.40 = $128.40
find the best unit price:
$1.79 per 10 ounces
$1.89 per 12 ounces
$5.49 per 32 ounces
1.79/10 = .179 per ounce
1.89/12 = .12.75 per ounce
5.49/32 = .172 per ounce
area
Length x Width
area of a circle
A=πr²
natural numbers
The set of numbers 1, 2, 3, 4, ... Also called counting numbers.
whole numbers
Natural numbers ( counting numbers) and zero; 0, 1, 2, 3...
