Answer:
Theoretical probability
Step-by-step explanation:
The theoretical probability is defined as:

In this case we look for the probability of taking a 2 out of the bag. As there is only one paper with the number 2 in the bag then:
number of desired results = 1
The amount of paper in the bag is equal to 7, so:
number of possible results = 7
Thus:

This is a theoretical probability, since we do not need to perform the experiment to calculate the probability.
To calculate the experimental probability we must perform the following experiment:
Take a paper out of the bag, record the number obtained and then return the paper to the bag.
Now repeat this experiment n times. (Perform n trials)
So:

To calculate a theoretical probability you always need to perform an experiment with n trials.
Answer:The value of R at atm that is at standard atmospheric pressure is R = 8.3144598 J. mol-1. K-1.
Step-by-step explanation:i got this from someone
That’s the correct answer
Area of sandbox = 169 square feet
Area of square with side 'x' is given by the formula = 
We have to determine the total length of wood Drew needs to make the sides of the sandbox.
Total length of wood required would be equal to perimeter of sandbox.
Let 'a' be the side of the square sandbox.
So, Area of sandbox = 169


a = 13 feet
Total length of wood required to make sides of the sandbox = Perimeter of the square sandbox = 
= 
= 52 feet.
Therefore, 52 feet of wood is required to make the sides of the square sandbox.
C(0,4)
B to C is (+1,+4)
so A to D is also (+1,+4)
