How many combinations of seven numbers are there in the numbers 1 to 30?
If you want no repetition, and order does not matter, then it is given by the following formula:
C = N!/(R!(N-R)!), where N is the total number of items (N=30), and R is the number that you are taking at a time (R=7). The ! means factorial (7! = 7 x 6 x 5 x 4 x 3 x 2 x 1)
30!/(7!*(30-7)!) = 2,035,800. See related link on MathsIsFun.com
The answer is 30*29*28*27*26*25*24/(7*6*5*4*3*2*1) = 2035800
What is the greatest number possible with these digits 3 71 5?
you get the larger numbers first. remember that. that is the most important answer to these questions. the answer is 7531.
What is the mean median mode of 2619046?
The mean, median and mode of a single number is the number itself. So the answer to all three is 2619046.
What number is a square and is even and three digits and is a factor of three?
There is no such number which IS a factor of 3. All factors of 3 are less than 3 and the smallest 3 digit (whole) number is 100 which is greater than 3.
However if you meant HAS a factor of 3 (ie it is a MULTIPLE of 3), then:
Let x, y and z be whole numbers, then:
As the number is a square it is of the form x²
As the number is even, it must contain the factor 2; let x = 2y, then the number is of the form (2y)² = 4y²
As the number has a factor of 3; let y = 3z, then the number is of the form 4(3z)² = (4×9)z² = 36z²
The three digit numbers are100 to 999;
The first multiple of 36 which is greater than or equal to 100 is given by: 100 ÷ 36 = 2 7/9 → first multiple is 3 × 36 = 108
The last multiple of 36 which is less than or equal to 999 is given by 999 ÷ 36 = 27¾ → last multiple is 27 × 36 = 972
The solution is a multiple of 36 which is 36 multiplied by a square number between 3 and 27.
The square numbers between 3 and 27 are 2² =4, 3² = 9, 4² = 16, 5² = 25; thus the possible 3 digit numbers which are squares, even and haver a factor of 3 are:
4 × 36 = 144
9 × 36 = 324
16 × 36 = 576
25 × 36 = 900
What is the largest number can be formed using the number 2463?
Pressumably, you want to use each digit once. Starting from the left, use the largest digit you can every time. For example, the left-most digit should be "6".
What is the mode range and median of 898 101 3 31 51 58 13 14?
Median: 41
Mode: 898, 101, 3, 31, 51, 58, 13, 14
Range: 895
Is the random sample is the most important?
There is no "most" important. Different solutions are required for different circumstances.
How much sandstone will cover 400 square feet?
It depends to what depth. One cubic INCH will cover 400 square feet in sandstone dust but it will be only 0.00002 inches deep!
What is the probability that she will roll a number other than 1?
On a single toss of a six-sided die. The chance of rolling a one is 1/6, and the chance of not rolling a one is (1 - 1/6 = 5/6), or 83.333 %

How many 5 number combinations there are from 1 to 26?
The answer is 26C5 = 26*25*24*23*22/(5*4*3*2*1) = 65,780
How many different digits can be the units digit of an integer perfect square?
Six: 0, 1, 4, 5, 6 and 9
What would the data set look like if you have only one whisker in the box plot?
If you do not have the left side whisker, it means that the minimum value and the lower quartile are the same. This means that the smallest 25% of the observations (or more) are all the same.

Why odd number cannot exist in nomal distribution?
It's not clear to me what this question means.
Any real number between negative infinity and positive infinity can arise from a population with a normal distribution, and this clearly includes odd numbers.
What do you mean by commercial products?
well commercial products is really thing like doritos or phone commercials where the consumer presists that his/her product is best.
