Probability
If you flip three coins, what is the probability that all three will be heads?
1/8
If the equation is y=-2x+1 what would the range be, given the domain (-1, 0, 1, 2)
(3, 1, -1, -3)
Identify all subsets of the Real Number System that 13/5 belongs to.
Real/Rational
If angle a is vertical to angle b and angle a is 40 degrees, what is angle b?
40 degrees. Vertical angles are opposite and equal.
4x-9=11

When you roll a number die and then flip a coin, what is the probability that will land on a 2 OR 4 and get a Head?
1/6
Will this graph be positive or negative? y=2x-4 You must tell me why
Positive because the slope (x value) is positive 2 X. The negative 4 has nothing to do with the slope.
Identify all subsets of the RNS that 0 belongs to
Whole/Integer/Rational/Real
Angle R is 130 degrees. What is angle F, if angles F and R are Supplementary?
50 degrees
2(3x-7)=29 Solve for X and identify the first property used in solving for X
7.16 and distributive property.
There are 5 red, 3 blue and 2 yellow marbles in a bag. What is the probability you would pick two red marbles if you didn't replace it after each draw?
2/9
Where does this equation cross over the y intercept y=-5x+2
y= +2
Order in descending order: 6/9, 31%, 9/6, .32
1) 9/6
2) 6/9
3) .32
4) 31%
If an angle is 14 degrees, identify it's compliment, supplement.
Compliment: 76 Supplement: 166
3n-9-2n= -n+3
n=6
If i roll three dice, what is the probability that I will get an even number on the first, a 6 on the second and a 4 or 5 on the third.
1/36
If the coordinates for a function are (0, 2) (-1, 4) (-2, 6) . (3, -7)... Identify the range (output)
The range (output) are the y values -- they would be 2, 4, 6, -7
Identify the only natural number between 341% and 19/4

The two characteristics of Adjacent angles are:
They share a vertex and a side.
3(r-4)+r=r+2+r
r=7
There are 5 red, 3 blue and 2 yellow marbles in a bag. Is there a better probability of picking a blue then a yellow without replacing them after each draw or picking a blue then a yellow with replacement. You must show your work!
Without replacement: 6/90 (6.7%) chance
With Replacement: 6/100 (6%) chance.
Find the rule given the ordered pairs (0, -3) (-1, -5) (1, -1) (2, 1)
Hint: might help to put them in a x/y table (vertical or horizontal) to see the pattern
y= 2x-3
What is the difference between rational and irrational numbers?
Rational numbers end or go on forever with a pattern. Irrational numbers go on forever with no pattern.
Can angles be adjacent and vertical?
No. Adjacent angles are "next" to each other. Vertical angles are across from each other.
