Step-by-step explanation:
Answer: 400 adult tickets were sold.
Step-by-step explanation:
Let x represent the adult tickets that were sold.
Let y represent the number of children tickets that were sold.
1000 tickets were sold to the seaport aquariums dolphin show. This means that
x + y = 1000
Adult tickets cost $10. Children tickets cost two dollars and a total of 5200 was collected. This means that
10x + 2y = 5200 - - - - - - - -1
Substituting x = 1000 - y into equation 1, it becomes
10(1000 - y) + 2y = 5200
10000 - 10y + 2y = 5200
- 10y + 2y = 5200 - 10000
- 8y = - 4800
y = - 4800/ - 8
y = 600
x = 1000 - y = 1000 - 600
x = 400
The winning probability is 1/3.

What is probability?</h3>
- A probability is a number that represents the likelihood or chance that a specific event will occur.
- Probabilities can be stated as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.
To find the winning probability:
- Favorable outcomes to win are 3 and 6.
- Total outcomes are 6in fair dice.
- To win $20 × 3 or $20 × 6 favorable outcome is 1 (3 and 6 respectively).
- The probability is 1 / 6.
- So, the probability of winning some money = 2/6 = 1/3
Therefore, the winning probability is 1/3.

The volume of a cube formula is v(s)=s^3. If you plug in 3 for s, you will find that v(s) would in fact equal 27. Thus the length of the sides are 3 and the volume is 27.
