Answer:
1/9.
Step-by-step explanation:
There is a total of 15 cards in the stack.
Prob( Queen is chosen) = 5/15 = 1/3.
The probability of a second queen being chosen is also 1/3
Required probability = 1/3 * 1/3 = 1/9.
The commutative property implies that, the order of multiplication is not important.
is true
Commutative property of multiplication states that:
If 
The expression is given as:

To get the commutative expression, we simply change the position of each factor in the expression.
So, some possible equivalent expressions are:

Answer:
Use SAS to show that triangles PRQ and PRS are congruent.
Step-by-step explanation:
Since PR bisects angle QPS, angles QPR and SPR are congruent. By reflexive property of congruence, PR is congruent to itself. Since PQ is congruent to PS, we can use SAS to show that the two triangles are congruent. By CPCTC, QR is congruent to SR.
Answer:
The parent function for a quadratic is f(x) = x^2. If there is something other than this, that is how you know it is a quadratic transformation.
No. There are 3 types of triangles.
Scalene: Triangle which no sides are equal, so all angles aren't congruent
Isosceles: A triangle with 2 equals sides, but has 1 not equal sides.
Equilateral: A triangle which all sides are equal
