Theoretical probability is the likelihood of a certain event occurring calculated based on all the possible outcomes. (Theorizing about the probability of a certain occurrence)
Experimental probability is the likelihood of a certain event occurring calculated by performing trials of an activity and recording the number of times an event occurs, then dividing the total number of even occurrences by total number of trials. (Experimenting to find probability of a certain occurrence)
Step-by-step explanation:
use the identity a²-b²=(a-b)(a+b)
x²-4=(x-2)(x+2)
so the answer is x-2
Answer:
x∈ (32,∞)
Step-by-step explanation:
x/8>4
x/2^3>4
x> 8*4
x>32
x∈ (32,∞)
1. Diagonals of kite bisect each other but kite is not parallelogram.
2. Square - the diagonals bisect each other
3. Rhombus - the diagonals bisect each others.
Not all parallelogram have their diagonals bisecting each other.
Let

be the number of 49 cent stamps bought and

be the number of 34 cent stamps bought. We can set up the following equations using the information above:


Substituting the first equation into the second equation will give you the following:

Solving for B will give you the number of 34 cent stamps purchased, and then you can figure out the number of 49 cent stamps purchased.
