Consider this three-digit sequence: 943. Is the first digit the largest or the second digit the smallest, AND, is the third digi
wolverine [178]
The sequence: 9, 4, 3

The largest number in this sequence is 9.
This is because 9 is of greatest value, being farther from 0 than the numbers 3 and 4.

The smallest number in this sequence is 3.
This is because 3 is of least value, being closer to 0 than the numbers 4 and 9.

Knowing this, we can answer the first question- "Is the first digit the largest or the second digit the smallest?"

9 is the first digit in this sequence, and it is the largest.
4 is the second digit in this sequence, and it is not the smallest. 3 is the smallest value in the sequence, but it is not the second digit.

This means that "the first digit is the largest" is the correct answer to the first question.

Even numbers result in integers, numbers without decimals/fractions, when divided by 2.

3 is an odd number, since it does not result in an integer when divided by 2.
3 is the third number in this sequence.

9 is also an odd number for the same reason.
9 is the first number in this sequence.

Knowing this, we can answer the second question- "Is the third digit even or the first digit odd?"

3 is the third digit in the sequence, and it is odd, not even.

9 is the first digit in the sequence, and it is odd.

This means that "the first digit is odd" is the correct answer to the second question.

Answers:
1) The first digit, 9, is the largest digit in the sequence.
2) The first digit, 9, is odd.

Hope this helps!

astra-53 [7]

Answer: A.4/52

B.1/52

C.4/42

D.12/52

Step-by-step explanation:

A. Because there is 52 cards in a deck the answer will be out of 52. Since there is 4 aces in the whole deck the probability of player one getting all four aces is a 4/52.

B. Since there is 52 cards in a deck and only one ace of hearts it will be a probability of 1/52.

C. Since there are 52 cards in a deck the probability that they will hold an ace card is a 4/52 Bc there are four aces.

D. Because there are 52 cards in a deck, and 12 hearts in the deck in all they will have a chance of 12/52

You might need to simplify these fractions or convert to a percentage based on what your instructor wants.

rooks are randomly placed on different squares of a chessboard. A rook is said to attack all of the squares in its row and its c
Olegator [25]

Answer: 2*8^{8}-8!

Step-by-step explanation:

We can place a rook in each row in 8^{8} ways.

We can place a rook in each column in 8^{8} ways.

So the total ways in which we can place a rook in a row or column is 2*8^{8}

Now there are 8 ways to choose the column for the first row, 7 ways to choose the column for the second row, and so on. So there are 8! ways to choose a column for a row.

So, we get the final answer by subtracting the 8! from the total ways a rook can be placed which is 2*8^{8}-8! when binomial coefficients are not evaluated
