For this case we propose a system of equations:
x: Variable representing the weight of large boxes
y: Variable that represents the weight of the small boxes
So
We clear x from the first equation:
We substitute in the second equation:
We look for the value of x:
Large boxes weigh 50 pounds and small boxes weigh 30 pounds
Answer:
Large boxes weigh 50 pounds and small boxes weigh 30 pounds
Answer:
There are 2,598,960 5 draw poker hands are there.
There are 311,875,200 5-stud poker hands.
Step-by-step explanation:
When the order is not important, we use the combinations formula:
For example, eating an apple and an orange is the same as eating an orange and an apple.
is the number of different combinations of x objects from a set of n elements, given by the following formula.
When the order is important, we use the permutations formula:
For example, a 3 digit credit card password, 123 is different than 213.
The number of possible permutations of x elements from a set of n elements is given by the following formula:
A hand of 5-card draw poker is a simple random sample from the standard deck of 52 cards. How many 5 draw poker hands are there?
Here, the ordering is not important, so we use the combinations formula.
There are 2,598,960 5 draw poker hands are there.
In 5-card stud poker, the cards are dealt sequentially and the order of appearance is important. How many 5-stud poker hands are there?
The ordering is important, so we use the combinations formula.
There are 311,875,200 5-stud poker hands.
