yan [13]

Answer:

There are 2,598,960 ways to receive 5 cards from a deck of 52.

Step-by-step explanation:

The order in which the cards are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

a. How many ways are there to receive 5 cards from a deck of 52?

C_{52,5} = \frac{52!}{5!(47)!} = 2598960

There are 2,598,960 ways to receive 5 cards from a deck of 52.

The sum of three numbers is 69. The second number is 6 less than the first. The third number is 3 times the first. What are the
almond37 [142]

Answer and Step-by-step explanation:

To solve, we would set the first number to x, and make an equation.

<u>Solve for x.</u>

x + (x - 6) + 3x = 69.

<u>Add and combine like terms.</u>

2x + 3x - 6 = 69

5x - 6 = 69

<u>Add 6 to each side of the equation.</u>

5x = 75

Divide by 5 to both sides.

x = 15

<u>The first number is 15.</u>

<u>The second number is (x - 6) = (15 - 6) = 9.</u>

<u>The third number is 3x = 3(15) = 45.</u>
