ANSWERS
Given m the m following m set m of m numbers: m 3.3, m -2.3, m -
16, m 25. m What m are m the m square m roots m of m the m whole m number?
A. m +/- m 2.3
B. m +/- m 3.3
C. m +/- m 4
D. m +/- m 5 m - m CORRECT m ANSWER m -D. m +/- m 5
Composite m Number m - m CORRECT m ANSWER m -A m number m with m more m factors m that
m just m one m and m itself.
Equivalent m Fractions m - m CORRECT m ANSWER m -Different m fractions m that m represent m the
m same m value.
,X-Axis m - m CORRECT m ANSWER m -
The m horizontal m line m that m passes m through m the m origin m on m a m coordinate m plane.
Qualitative m Data m - m CORRECT m ANSWER m -Non-
numeric m information m based m on m some m quality m or m characteristic.
No m Correlation m - m CORRECT m ANSWER m -
There m is m no m apparent m overall m trend m between m the m two m variables. m If m the
m correlation m coefficient m is m 0, m th mis m only m rules m out m a m linear m trend.
m There m could m be m a m non-linear m or m curvilinear m trend.
Extrapolate m - m CORRECT m ANSWER m -
Using m information m from m a m data m set m to m make m predictions m about m data m outside
m of m the m original m set.
Event m - m CORRECT m ANSWER m -
An m outcome, m or m set m of m outcomes, m whose m chance m of m occurrence m can m be
m represented m with m a m probabili mty.
, Given m the m following m set m of m numbers: m 10, m 2.5, m -4, m -
4.5, m 5. m What m is m the m sum m when m adding m together m only m the m whole
m numbers?
A. 5.5
B. 11
C. 12.5
D. 15 m - m CORRECT m ANSWER m -D. m 15
Operation m - m CORRECT m ANSWER m -
In m Mathematics, m an m operation m is m a m procedure m which m generates m a m new
m value m from m one m or m more m oper mands, m or m Mathematical m values.
Conditional m Proportion m - m CORRECT m ANSWER m -
A m proportion m where m one m part m of m the m proportion m is m a m variable, m or
m unknown m quantity.
Coefficients m - m CORRECT m ANSWER m -
A m number m by m which m a m number m is m multiplied. m This m number m is m written m in
m front m of m the m variable(s).
Mean m - m CORRECT m ANSWER m -
Average, m calculated m by m adding m a m series m of m elements m in m a m data m set
m together m and m dividing m by m the m total mnumber m in m the m series.
