What does weigh the possible outcomes mean?

Oh, dude, weighing the possible outcomes just means considering all the different results that could happen from a decision or action. It's like mentally comparing the options on a cosmic scale, you know? So, like, make sure to think about the consequences before you dive into anything, or you might end up in a real pickle.

How many combinations of 3 words?

To determine the number of combinations of 3 words, we need to know the total number of words available. Let's say we have a pool of n words. The formula to calculate the number of combinations of 3 words without repetition is n! / (3!(n-3)!), where "!" denotes factorial. This formula accounts for the number of ways we can select 3 words from a pool of n without repetition.

What does metza metza mean?

How many city of Milwaukee blocks are in a mile?

Oh, dude, you're really testing my math skills here. Okay, so one mile is equal to 5,280 feet, and a typical city block is around 330 feet, so if we do the math, that's like 16 city blocks in a mile. But hey, who's counting, right?

The largest 12- digit number where repeated digits are allowed?

Well, honey, the largest 12-digit number with repeated digits allowed is 9,999,999,999,999. I mean, unless you want to get fancy and start throwing in letters or emojis, but I doubt that's what you're looking for. So there you have it, the biggest 12-digit number you can get with the same digit repeated over and over again.

What is the greatest difference you can get when you subtract a 3 digit number from a 4 digit number?

Largest 4 digit number = 9999 Smallest 3 digit number = 111 9999 - 111 = 9888 Largest 4 digit number = 9999 Smallest 3 digit number = 111 9999 - 111 = 9888

What is the sample space of rolling a number cube twice?

When rolling a number cube (a six-sided dice) twice, the sample space consists of all possible outcomes from both rolls. Since each roll has 6 possible outcomes, the total number of outcomes for rolling the number cube twice is 6 x 6 = 36. The sample space would be {1-1, 1-2, 1-3, ..., 6-5, 6-6} representing all possible combinations of the two rolls.

What is a disadvantage of using a stem and leaf plot?

Some disadvantages: Cannot be used for categorical data. Difficult with large number of observations. Not very good if there are many stems with no leaves (you must show bare stems). This can be a problem if there are outliers. Ideally require leaves to be ordered on each stem - hard work. Tricky to use (though not impossible) if decimal stem/leaf are not the optimal solution.

What kinds of numbers would I multiply by to get answers that are slightly greater than my starting number?

If you multiply your number by any number greater than 1, the result will be greater than the starting number - assuming your number is positive. If your number is negative, you need to multiply it by any number less than 1, to get a result that is greater than the original number.

To get a number that is slightly greater, multiply by a number that is slightly greater than 1 (ot slightly lee than= -1).

How many numbers can you make with 4 digits used only once?

Well, darling, if you're using 4 digits and each one can only be used once, you can make a total of 9,720 different numbers. That's because you have 10 choices for the first digit, 9 choices for the second digit, 8 choices for the third digit, and 7 choices for the fourth digit. Multiply all those together and voilà, you've got yourself a whole lot of numbers to play with.

What percent of a normal population is within 2 standard deviations of the mean?

In a normal distribution, approximately 95% of the population falls within 2 standard deviations of the mean. This is known as the 95% rule or the empirical rule. The empirical rule states that within one standard deviation of the mean, about 68% of the population falls, and within two standard deviations, about 95% of the population falls.

How many sum of the digit is nine?

To determine how many numbers have a sum of digits equal to nine, we consider the possible combinations of digits that add up to nine. These combinations include (9,0), (8,1), (7,2), (6,3), and (5,4). Therefore, there are five possible combinations of digits that sum up to nine.

How do you read a balance scale?

To read a balance scale, first ensure it is calibrated and leveled. Place the object being weighed on one side of the scale and add standard weights to the other side until the scale balances. The weight of the object is equal to the sum of the standard weights on the other side. Record the weights used and add them up to determine the weight of the object.

What percentage of abused individuals grow up to be abusers?

Research shows that not all individuals who have experienced abuse in childhood will go on to become abusers themselves. However, there is a correlation between childhood abuse and later perpetration of abuse. Studies suggest that around 30% to 40% of individuals who have been abused may become abusers later in life. It is important to note that this percentage can vary based on individual factors, such as access to support services and therapy.

How many number combinations for 9 digits?

999,999,999 if you don't include 000000000, otherwise 1,000,000,000.

If you don't allow repeated digits then 9 factorial, ie 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 = 362,880.

What is two thirds of 70?

Well, isn't that a happy little math problem! Two thirds of 70 is like painting a beautiful picture with numbers. Simply divide 70 by 3 to get 23.33, then multiply that by 2 to get 46.67. So, two thirds of 70 is 46.67. Just remember, there are no mistakes in math, only happy little accidents.

What is the answer X is a missing number x has 3 digits the tens digit is half the hundreds digit thenumber is odd the sum of the digits is 9 what is x?

Well, isn't that just a happy little mystery we have here! Let's take a closer look at our clues. If the tens digit is half the hundreds digit and the sum of the digits is 9, we can see that the hundreds digit must be 6, the tens digit is 3, and the units digit is 0. So the missing number X is 630. Happy solving, my friend!

In oz lotto how many numbers do you need to win?

In Oz Lotto, players need to select 7 numbers from a pool of 1 to 45 numbers to win the jackpot. The winning numbers are drawn randomly, and if a player's chosen numbers match all 7 drawn numbers, they win the jackpot prize. Matching fewer numbers can also result in winning lower-tier prizes.

What are the 10000 different combinations to a four digit number?

Oh, isn't that a happy little question! There are 10,000 different combinations for a four-digit number because each digit can be any number from 0 to 9. Just imagine all the beautiful possibilities you can create with those numbers. Remember, there are no mistakes, just happy little accidents in the world of numbers.

Why inferential statistics is not required in census?

Inferential statistics is not required in a census because a census aims to collect data from every individual in a population, leaving no room for sampling error or uncertainty. The goal of a census is to provide an accurate count or measurement of a specific characteristic within a population, making the need for statistical inference unnecessary. In contrast, inferential statistics is used when data is collected from a sample of a population, and the goal is to make predictions or inferences about the larger population based on that sample.

What is the probability of getting stuck by lightning?

'Stuck' ???? Well lightning might stick you to the ground.

I think you mean 'struck'.

In a house, building, or a car, the probablity is very low.

However, on an open hillside/prairie the probability is much higher, because you are above the surrounding surface, and you act as a lightning antenna/conductor. Hence a strike us far more probable.

How can adding doubles help you to multiply by 2 example?

Adding doubles can help you multiply by 2 through the property of commutativity in multiplication. By adding two equal numbers together (doubles), you are essentially multiplying one of the numbers by 2. For example, 5 + 5 = 10, which is the same as 5 x 2 = 10. This strategy can simplify multiplication problems and help build a deeper understanding of the relationship between addition and multiplication.
