Math Review

Here are some question to help you on the exam ! please answer them !!.

Solve the algebraic equation

1) 5 = k + 2 2) 4y - 3= 9 3) a +4 = 15 4) 3n - 4 = 14

5) 7 k=14 6) c/7=3 7) 7=p/3 8) 6/j+2=10

/ means divide

Finding the mean , median and mode for each question

1) 3,34,6,6,8,7,,11,4,6 2) ,9,12,14,15,2,1,5,4,5,7,7,

Mesures Of Central Tendency

Common Denominators

A common multiple of the denominators of a set fractions

A common denominator for 1 over 4 and 1 over 6 is 12 because a common multiple of 4 and 6 is 12



Multiples ( skip count )



The product of a given number and a natural number like 1,2,3 and so on



For example some multiples of 3 are 3,6,9,12



1x3=3 ,2x3=6, 3x3=9,3x4=12



List 5 multiples of 4



Don't find factors



4,8,12,16,20,24



1 over 2 and 2 over 3 find common denominator

(find multiples first than find LCF )



multiples of 2 are 2,4,6,8,10 multiples of 3 are 3,6,9,12,15



The LCF is 6 so



1 x3 3

2 x3 6 What you do to the bottom you must do to the top



2 x2 4

3 x2 6 What you do to the bottom you must do to the top

Math notes for lowest terms

LOWEST TERMS-A fraction is in lowest terms when the numerator and denominator of the fraction have no common factor other than 1

Answer To Paulo's Scribepost

His question was :
Billibob has a box of dodge balls in that box there are 8 dodge ball in different colours green ,black , blue , pink , white , Red , brown , yellow .what is the possible out come of Billibob getting blue ?

All the possible out comes of Billibob getting blue are :

Probability

There is a hat with 4 different flavours of ice cream and 2 different cones 1 strawberry , 2 chocolate ,3 mint , 4 vanilla and the two different cones are 1 sugar cone and 2 waffle.What is the probability that Vinny with pick (strawberry) and (sugar cone ).

A) What is the sample space of this experiment?

B)Organize the outcomes of these events any way you want?

C)What Are the outcomes independent?

Question 8-10

For number eight you have to make two different method of perpendiclar bisectors

Method one

1. draw a line segment
2. sharp end of the compass
3. make an arc slightly larger than half the length of theline segment
4. repeat the process from point B with the same sized arc
5. with a ruler join the two arc intersection with a atraight line
6. now you have a perpendicular bisector

Kyia Order of operations

B- brackets ( )
E- exponents 92
D- division (in the order from left to right)
M- multiplication
A- addition ( in the order from left to right)
S- subtraction

1. Annie has been ask to calculate 1.7+6/2 she claims the answer is 3.83 do you agree ? why or why not ?

2. I don't agree because she didn't follow BEDMAS because division come before adding so she should on got 4.7












Put brackets in the following expression to get the largest value possible what problem solving strategy did you use 3x2.8+6.4\4

1. (3x2.8)+6.4\4=10 .

create a problem that could be solved using the following expression 2.5 +1.25+5 x1.6

Kyia wanted to get a pack of Kit-Kat's they cost 11.75 and she only had 9 dollars so she started to sing and she got 2 dollars but she still needed 75 cents so she looked around out and got 75 cents and now she can buy Kit-Kat's

Test correction for question 9

• 9. Which point on the coordinate grid has coordinates (-1,2) ?

• The answer is B on the paper , and its quadrant 2 on the coordinate grid.

• The way to get the answer is looking on the coordinate grid , See its asking you what point on the coordinate grid has the coordinates (-1,2) so you look and its in quadrant 2 because you look on the x-axis and that's were -1 is and you look on the y-axis and that's were 2 is
