Make numbers 1-50 using 4 4's?
Oh, what a happy little challenge! Let's see here. We can make numbers 1 through 50 using four 4's by combining them with mathematical operations like addition, subtraction, multiplication, and division. It's all about being creative and seeing the beauty in numbers. Just remember, there are no mistakes, only happy little accidents in math!
What is the difference between a favourable outcome and a possible outcome?
A favorable outcome refers to a specific result that is considered desirable or advantageous in a given situation. On the other hand, a possible outcome is any potential result that could occur, regardless of desirability. In probability theory, the likelihood of a favorable outcome is often calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
What is the median of 15 18 22 11 20 20 13?
To find the median in a group of numbers, you need to arrange the numbers from least to greatest, and find the one in the middle. (It's pretty simple if you have an odd number of values, but if you have an even number of values, you can add the two in the center and divide them by 2.
The numbers you listed, when put in order from least to greatest, are:
11 13 15 18 20 20 22
If you look at it for a second, you'll see that the number in the center is 18. So, the median is 18.
How many combinations can you make with 1000 numbers?
There are 21000 - 1 combinations.
Remember that in a combination the order of the numbers does not matter. That is relevant only for permutations which are not the same thing.
For each combination, each one of the 1000 numbers can be in or out. So for each combination there are 1000 choices of in or out. Except that if all are out, you get a null combination - that is, a combination with no numbers. For that particular case you subtract the 1 from the total.
You will have 1 combination consisting of 1000 numbers, 499500 of 2 numbers and so on. The number of combinations will be the nth row of Pascal's triangle.
How do you state that your hypothesis was correct?
just say
"my hypothesis was correct because" and then state all the data that supports ur answer
What is the value of the digit 7 in the number 709?
In the number 709, the digit 7 is in the tens place. Therefore, its value is 7 multiplied by 10, which equals 70. The digit 7 represents 70 in this number, as it is in the tens place.
How many 3 number combinations can you make from 1 2 3 4 5 using each number once?
123, 124, 125, 132, 134, 135, 142, 143, 145, 152, 153, 154
213, 214, 215, 231, 234, 235, 241, 243, 245, 251, 253, 254
312, 314, 315, 321, 324, 325, 341, 342, 345, 351, 352, 354
412, 413, 415, 421, 423, 425, 431, 432, 435, 451, 452, 453
512, 513, 514, 521, 523, 524, 531, 532, 534, 541, 542, 543
A total of sixty combinations.
You could also use the Permutation formula with no repetition to get the result, without having to list them all out. This is important once you start getting into higher numbers.
The formula is n! / (n-r)! where n is the total number of items, and r is the number of items you are taking for each permutation.
The exclamation (!) means factorial. You take n * (n-1) * (n-2) * (n-3) * . . . . * 1.
In this case n=5 and r=3
so 5! / (5-3)! = (5 * 4 * 3 * 2 * 1) / (2 * 1) = 120/2 = 60. I'm posting a link for more information.
What is the next number in the series 1 9 18 25 27 21?
The series appears to be following a pattern where each number is the result of a mathematical operation on the previous numbers. In this case, the pattern seems to be adding consecutive odd numbers starting from 1.
1 + 8 = 9 9 + 9 = 18 18 + 7 = 25 25 + 2 = 27 27 - 6 = 21
Following this pattern, the next number in the series would be 21 + 1 = 22.
What are several types of graphs?
Several types of graphs include bar graphs, which represent data using rectangular bars of varying lengths; line graphs, which show trends and changes over time using lines connecting data points; pie charts, which display data as a circular graph divided into slices to represent proportions; and scatter plots, which show the relationship between two variables by plotting points on a graph. Each type of graph is used to visually represent different types of data and relationships.
What are things that come in groups of seven?
1) Harry Potter the quidditch matches have 7 team mates on each team=]
2) Seven swans a-swimming
3) Each Ultimate team has 7 players on the field
4) Dwarfs
5) a winning streak in a game of craps
6) seven years of bad luck if you break a mirror
How many 4 digit numbers can be formed using the digits 1 3 5 7 9?
Using only the numbers 1,3,5,7,9, and using each number only once, we have 5 options for the first digit, then 4 remaining options for the second, 3 remaining options for the third and 2 remaining options for the fourth. This means there are 5x4x3x2 ways to combine the digits 1,3,5,7,9 into a 4 digit number. 5x4x3x2=120, so there are 120 four digit numbers that can be made.
How do you find the median with an even data set?
The median is the mean of the middle two.
For example, find the median of the set {1, 3, 4, 6, 9, 10, 15, 20}.
There are 8 items in the data set, so the median is the mean of the middle two.
The middle two are the 4th and 5th data items: 6 & 9
median = mean of 6 & 9 = (6 + 9)/2 = 7.5
Well, honey, you're looking for a number that's divisible by 8 and by 9, a three-digit multiple of 10, and falls between 200 and 700. The only number that fits the bill is 360. So there you have it, 360 is the magic number you're searching for.
What do the numbers on the syringe mean?
How many millimeters of whatever medication is in the syringe
To simplify the ratio 21 to 27, you need to find the greatest common divisor (GCD) of the two numbers, which is 3. Divide both numbers by 3 to simplify the ratio: 21 ÷ 3 = 7 and 27 ÷ 3 = 9. Therefore, the simplified ratio of 21 to 27 is 7 to 9.
Judy tosses a coin 4 times draw a tree diagram?
To draw a tree diagram for Judy tossing a coin 4 times, we start with the initial toss, which branches into two possibilities: heads or tails. Each subsequent toss branches out in the same manner. So, the first level of the tree diagram will have 2 branches, the second level will have 4 branches, the third level will have 8 branches, and the fourth level will have 16 branches, representing all possible outcomes of tossing the coin 4 times.
What is greater 10.30 or 10.3?
Well, my friend, when we look at 10.30 and 10.3, we see that they are very close in value. The number 10.30 has an extra zero after the decimal point, making it slightly greater than 10.3. Just remember, whether it's a big difference or a small one, every number has its own special beauty.
How many movies are made each year?
Th MPAA keeps current statistics on this. Go to http://www.mpaa.org/policy/industry.
North American movie releases for 2007, 2008 and 2009, were 609, 633 and 558 respectively. The downturn in 2009 was the first decline since 2003 and was due to labour issues in 2007-8 and the recession.
As the numbers 1 to 99 are multiplied together, one factor of the product will be 10 which means the last digit must be 0 (a zero).
Without working out the product, it can be seen that every multiple of 5 in the original numbers can be paired up with an even number (that is not a multiple of five) and multiplied together (which produces a multiple of 10) which are all factors of the product together; thus the product will ends with that number of zeros: there are 19 multiples of 5 in the numbers 1-99, so the last 19 digits of the product are all 0 (zero).
