What is the probability number is perfect square from 10 to 20?
There are 11 numbers from 10 to 20 if we include 10 and 20. Of those, only 16 is a perfect square. So the probability if 1/11 or .09 repeating.
If the 25 question test was true or false what is the probability that you can guess and get all correct perfect paper?
The probability is (1/2)25 = 1/33554432 = 0.00000003, approx
Probability of getting a perfect score in a three question true or false quiz?
If you answer randomly, 1 in 8.
What is the probability that the sum of the numbers from two rolled dice result in a perfect square or even number?
Part1: Finding probability of getting sum as a perfect square. Maximum sum of both the dice is (6+6) equal to 12. Up to 12, the perfect squares are: 1, 4 and 9. Getting a sum of 1 from two dice is not possible. So, we are left with 4 and 9. To get 4, the combination can be: (2,2) or (1,3) or (3,1). This means, to get the sum as 4, the probability is [3/36]. To get 9, the combination can be: (3,6) or (6,3) or (5,4) or (4,5). This means, to get the sum as 9, the probability is [4/36]. Therefore,the total probability of getting the sum as a perfect square is: [(3/36)+(4/36)]=[7/36]. Part2: Finding the probability of getting sum as an even number. The possible even numbers can be 2, 4, 6, 8, 10 and 12. But, as 4 is already considered in part1, it should be ignored in this case. The probability of getting sum as 2 is: [1/36] The probability of getting sum as 6 is: [5/36] The probability of getting sum as 8 is: [5/36] The probability of getting sum as 10 is: [3/36] By adding all the above, the probability of getting sum as an even number (ignoring 4) is: [(1/36)+(5/36)+(5/36)+(3/36)]=[14/36]. From part 1 and part 2, we get the total probability as [(7/36)+(14/36)]=[7/12]=0.583333.
How many three digit positive integers are square numbers?
102 = 100 which is the first possible three digit number that is a perfect square. 312 = 961 which is the last possible three digit number that is a perfect square. So there are 22 three digit positive numbers that are perfect squares.
What does perfect whole and complete have to do with integers?
and integer has to be whole
Are square roots of positive integers rational?
Only if the integer is a perfect square.
Is the product of two perfect squares sometimes a perfect square?
yes..always a perfect square A perfect square is the product of an integer by itself. If you multiply a perfect square x² by another perfect square y² you get x²y² = x·x·y·y = x·y·x·y = (x·y)² which is a perfect square. Note that the product of two integers will also be an integer so x·y must be an integer because if x² and y² are perfect squares x must be an integer and y must be an integer and x·y is therefore a product of 2 integers.
Why are all the perfect squares are rational number?
A perfect square is a square of an integer.The set of integers is closed under multiplication. That means that the product of any two integer is an integer. Therefore the square of an integer is an integer.Integers are rational numbers so the square [which is an integer] is a rational number.
What is the probability of two positive integers under 100 being perfect squares?
It is 36/9702 = 0.0037 approx.
Find a positive integer such that the integer increased by 1 is a perfect square and one-half of the integers increased by 1 is a perfect square?
0
Is 17 a perfect square and why?
No. There are no integers that when multiplied by themselves equal 17.
Is the square root of 170 a rational number?
No. The only square roots of integers that are rational numbers only when the integer is a perfect square.
What is the smallest integer where the integer before it is a perfect square and the integer after it is a perfect cube?
The integer is 26
What are the perfect square integers between 1 and 81 inclusive?
1,4,9,16,25,36,49,64,81
What is the probability that a randomly selected two-digit positive integer is a perfect square or a perfect cube?
There are 90 two-digit numbers from 10 to 99. Of those, 6 are perfect squares (16, 25, 36, 49, 64, and 81) and 2 are perfect cubes (27 and 64). Each perfect square or root has a probability of 1 in 90 in being drawn.
How many 5-digit integers are perfect squares?
The smallest 5-digit integer perfect square is 10,000 = (100)2The largest 5-digit integer perfect square is 99,856 = (316)2So we want to know how many numbers that is, from 100 to 316 inclusive.It's 316 minus the first 99 = 217 of them.
