A six-sided number cube labeled 1 through 6 is rolled 500 times. An odd number is rolled 325 times. Compare the experimental probability of rolling an odd number with the theoretical probability of rolling an odd number and select one of the statements below that best describes the situation.
The experimental probability and theoretical probability are the same.
The experimental probability is larger than the theoretical probability.
The experimental probability is smaller than the theoretical probability.
There is not enough information to determine the relative frequency.

The experimental probability is larger than the theoretical probability.
Step-by-step explanation:
On a six-sided number cube labeled 1 through 6, there are 3 odd numbers and a total of 6 numbers. The chance of rolling an odd number is 3/6, or 1/2.
The theoretical probability would be 1/2.
After rolling the cubs 500 times, an odd number is rolled 325 times. This means that 325/500, or 13/20, of the time, an odd number is rolled.
The experimental probability would be 13/20.
1/2 can be rewritten as 10/20.
13/20 > 10/20
Since 13/20 is greater than 10/20, the experimental probability is larger than the theoretical probability.
The experimental probability is larger than the theoretical probability.
I hope this helps. :)

Step-by-step explanation:
A will.
Suppose the object is placed on (5,4)
If you rotate it 180o counterclockwise, the point will become (-5,-4) (both x and y will change signs.)
Moving one unit down will still leave you in quadrant III.
If you start in another quadrant, this answer will not be correct. If the point started out in quadrant 2, rotating it 180o counterclockwise will put you in quad 4. For example
Object Start: (-2,3) Starts in quad 2
Image found: (- -2, - 3) = (2, - 3) which is in quad 4.
