What is maximum and minimum electric flux?

As we know that electric flux is the total number of electric lines of forces passing through a surface.

Maximum Flux:

Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface.

Minimum flux:

Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.

What is the formula in getting Mean Percentage score?

The formula for calculating the mean percentage score is to first add up all individual scores, then divide the total by the number of scores. This will give you the mean score. To convert the mean score to a percentage, you would then divide the mean score by the total possible score and multiply by 100. This will give you the mean percentage score.

A bag contains 6 orange 7 green and 8 yellow marbles Find the probability of picking 3 yellow marbles if each marble is returned to the bag before the next marble is picked?

Well, honey, if you're reaching into that bag three times and each time you're pulling out a yellow marble and then putting it back in, the probability of picking a yellow marble each time is 8/21. Multiply that by itself three times because you're picking three marbles, and you get a probability of 512/9261. So, good luck with those yellow marbles, darlin'!

How many 3 digit numbers are multiples of 5?

To determine the number of 3-digit numbers that are multiples of 5, we need to find the first and last 3-digit multiples of 5. The first 3-digit multiple of 5 is 100, and the last 3-digit multiple of 5 is 995. To find the total number of such multiples, we can use the formula (Last - First) / 5 + 1 = (995 - 100) / 5 + 1 = 180. Therefore, there are 180 3-digit numbers that are multiples of 5.

What is 0.0004 as a percentage?

0.0004 = 0.04% (just move the decimal point two places to the right and put the percent symbol)

How many 7 number combinations from 8 numbers?

To calculate the number of 7-number combinations from 8 numbers, you can use the combination formula, which is nCr = n! / r!(n-r)!. In this case, n = 8 (total numbers) and r = 7 (numbers chosen). Plugging these values into the formula, you get 8C7 = 8! / 7!(8-7)! = 8 ways. Therefore, there are 8 different combinations of 7 numbers that can be chosen from a set of 8 numbers.

What is the probability of getting a picture card in deck of 52 cards?

There are 12 picture (or face) cards in a standard deck of 52 cards. The probability, then, of drawing a picture card is 12 in 52, or 3 in 13, or about 0.2308.

How many 7-digit phone numbers can be formed if the first digit cannot be 0 or 1 and no number can be repeated?

Oh, dude, let me break it down for you. So, since the first digit can't be 0 or 1, we have 8 options for that first digit. After that, we have 9 options for the next digit, then 8 for the next, and so on. So, it's like 8 x 9 x 8 x 7 x 6 x 5 x 4. Crunch those numbers and you get the total number of 7-digit phone numbers that can be formed without repeating any digits.

Non example for volume?

A line does not have a volume. Neither does a plane.

How to find the missing number if median is given?

The median is the middle number. If there is an odd number of numbers in the set, the median is the middle number, and the only way to find the missing number is if the median is the missing number. If there is an even number of numbers in the set, the median is the average of the two middle numbers, and the only way to find the missing number is if the median is one of those two numbers. If it is, you can take the median and the one of the two numbers you know. Use the formula (# +#)/2=median and solve.

What is the se mean and tr mean in statistics?

In statistics, the SE mean refers to the standard error of the mean, which is a measure of the variability of sample means around the population mean. It is calculated by dividing the standard deviation of the population by the square root of the sample size. On the other hand, the TR mean is not a standard statistical term. It's possible that it could be a typo or abbreviation for another concept, but without more context, it's difficult to provide a precise explanation.

0.02 level of significance what is the critical value?

The critical value for a 0.02 level of significance, denoted as α = 0.02, in a statistical test corresponds to the point on a distribution that separates the critical region (rejection region) from the non-critical region. To find the critical value, you would consult a statistical table or use a statistical calculator based on the specific test you are conducting (e.g., z-table, t-table, chi-square table). The critical value is chosen based on the desired level of significance, which represents the probability of rejecting the null hypothesis when it is actually true.

How many 3 digit numbers contain the digit 3 at least once?

172

==============================

Another contributor was amazed:

Wow ! That's a neat little problem.

Let's see . . . . .

-- There are three ways to have a single 3 in the number: 3xx, x3x, and xx3.

For 3xx, there can be 81 different numbers. (2nd and 3rd digits can't be a 3. 9x9=81.)

For x3x, there can be 72 numbers. (1st can't be 0 or 3. 3rd can't be a 3. 8x9=72.)

For xx3, there are also 72. (1st can't be 0 or 3. 2nd can't be a 3. 8x9=72.)

So far, we have 81+72+72 = 225 possibilities, with a single 3 in each one.

-- There are three ways to have two 3s in the number: 33x, 3x3, and x33.

For 33x, there can be 9 different numbers. (3rd digit can't be a 3.)

For 3x3, there can be 9 numbers. (2nd digit can't be a 3.)

For x33, there are 8 numbers. (1st digit can't be a 0 or a 3.)

So we have 9+9+8 = 26 more possibilities.

-- There is only one way to have three 3s in the number: 333.

That's one more possibility.

So the total number of 3-digit numbers where at least one of the digits is a 3 is

225 + 26 + 1 = 252 all together.

What do you call 14 digit number?

A 14-digit number is typically referred to as a "14-digit number." In mathematics, numbers are generally identified by the number of digits they contain, such as a 3-digit number, 7-digit number, etc. In computing, a 14-digit number may also be referred to as a "14-digit integer" or "14-digit numerical value."

What is the probability of 6 any numbers in lottery of 40 numbers?

Assuming there are six numbers drawn out of the set from 1 to 49, without replacement:

There are 15 out of 49 of these numbers that are prime. So the probability would be

(15 - 9)! / (49 - 43)! = (15 * 14 * 13 * 12 * 11 * 10) / (49 * 48 * 47 * 46 * 45 * 44)

= (24325271111131) / (27335172111231471) = (5 * 13) / (8 * 3 * 7 * 23 * 47)

= 65 / 181608

What is ramification means?

Answer

Ramification is usually used negitively to describe the results of a bad action. If you curse out your teacher, you must accept the ramifications (you'll get an 'F' this quarter).

Can you make all the numbers up to 100 using 1 2 3 4?

Yes, you can create all numbers from 1 to 100 using the numbers 1, 2, 3, and 4 along with basic mathematical operations. This includes addition, subtraction, multiplication, division, exponentiation, and concatenation. It requires creative combinations and sequences of these numbers and operations to generate each desired number within the range.

How many four digits numbers can be formed out of 56789 if no digits can be repeated?

To form a four-digit number without repeating any digits from 56789, we need to choose 4 different digits out of the 5 available. This can be done in 5 choose 4 ways, which is equal to 5! / (4! * (5-4)!) = 5 ways. Therefore, there are 5 four-digit numbers that can be formed out of 56789 without repeating any digits.

What body shape is 34 24 35?

Oh, dude, those numbers represent bust, waist, and hip measurements. So, technically, it's like a 34-inch bust, 24-inch waist, and 35-inch hips. But hey, who's counting? Just numbers on a tape measure, am I right?

Using all digits 1230 without repeating any digit how many four- digit numbers can you write?

Oh, dude, I mean, like, there are 4 digits in 1230, right? So you can totally make 4-digit numbers by using each of those digits once. That's like, 4 factorial, which is 24. So, you can totally write 24 different four-digit numbers using 1230 without repeating any digit. Easy peasy!

How many digits are there in the numbers 1 to 99?

Oh, what a delightful question! If we take a look at the numbers from 1 to 99, we'll find that they have a total of 189 digits. Each number from 1 to 9 has one digit, numbers from 10 to 99 have two digits each. Just imagine all those lovely digits coming together to create a beautiful numerical landscape!
