bar graph – a graph using vertical or horizontal bars to display numerical information.
Equivalent – same number of numbers
How is ratio expressed? – A ratio may be expressed as a fraction or it may be written using the colon (:) as the symbol or expressing ratio. Thus, the ration 5/7 may be written 5:7.
Angle measurements: 1 degree – 60 minutes
Divide – To split in half the divisor with the divided
proportional – An election system in which each party running receives the proportion of legislative seats corresponding to its proportion of the vote.
Find the mean, , for the binomial distribution which has the stated values of n and p. Round answer to the nearest tenth.n = 44; p = 0.2
Acute angle – An angle measuring less than 90degrees
Examples of Floor and Ceiling – floor(84.45) = 84
ceiling(84.45) = 85
floor(84.5) = 84
ceiling(84.5) = 85

floor(-2.3) = -3
ceiling(-2.3) = -2

Ratio – Expresses a relationship between two quantities; written in simplest form with fractions, colons, or words.
right triangle – contains a 90 degree angle
square numbers – eg 1,4,9,16,25… number…=square
10% – 0.10 (number times 0.10)
Find the meаn, , fоr the binоmiаl distributiоn which hаs the stated values of n and p. Round answer to the nearest tenth.n = 44; p = 0.2
Complementary angles theorum – Two angles that add to 90
prime number – an integer other than 1 that is divisible only by itself and 1
congruent angles – two angles that have the same measure.
Volume of a cylinder = – Area x height
