Equivalent expression of 9(r + r + r+ r)

In which number does the digit 4 have a value that is 10 times as great as the value of the digit 4 in 348,971? 284,796 or 327,4

Doss [256]

Answer:

The number is 492,875.

Step-by-step explanation:

Given:

A number that is = $348,971$

Place value of 4 = $40,000$

Place value is ten thousands.

We have to identify the number where the place value of 4 is 10 times of the given number.

Numbers given:

284,796 or 327,498 or 492,875 and 742,186.

Lets see the place value of 4 in each of the number.

⇒

$284,796$ place value of $4$ is $4,000$ .
Place value of 4 is thousands.

⇒

$327,498$ place value of $4$ is $400$ .
Place value of 4 is hundreds.

⇒

$492,875$ place value of $4$ is $4,00,000$ .
Place value of 4 is hundred thousands.

⇒

$742,186$ place value of $4$ is $40,000$ .
Place value of 4 is ten thousands.

Notes:

Ten thousands multiplied with ten is hundreds thousand.

⇒ $10,000\times 10 =1,00,000$

So,

The number which has digit 4 as hundred thousands place values is 492,875.

a student ran out of time on a multiple choice exam and randomly guess the answers for two problems each problem have four answe

katen-ka-za [31]

Answer:

The probability that he answered neither of the problems correctly is 0.0625.

Step-by-step explanation:

We are given that a student ran out of time on a multiple-choice exam and randomly guess the answers for two problems each problem have four answer choices ABCD and only one correct answer.

Let X = Number of problems correctly answered by a student.

The above situation can be represented through binomial distribution;

$P(X=r)=\binom{n}{r}\times p^{r}\times (1-p)^{n-r};x=0,1,2,3,....$

where, n = number of trials (samples) taken = 2 problems

r = number of success = neither of the problems are correct

p = probability of success which in our question is probability that

a student answer correctly, i.e; p = $\frac{1}{4}$ = 0.75.

So, X ~ Binom(n = 2, p = 0.75)

Now, the probability that he answered neither of the problems correctly is given by = P(X = 0)

P(X = 0) = $\binom{2}{0}\times 0.75^{0}\times (1-0.75)^{2-0}$

= $1 \times 1\times 0.25^{2}$

= 0.0625

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!
