Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons Neutrons (:
The only answers are 1 and 2. Meaning 1 and 2 are the only numbers that you can divide 170 and 12 by and get whole numbers (no decimals) as answers. 170 / 1 = 170 12 / 1 = 12 170 / 2 = 85 12 / 2 = 6 Try it with any other number and you'll see that at least one of your answers will not be a whole number.
183 and 185 are the nearest whole numbers. If you use decimals, then there are an infinite amount of answers.
There are an infinite number of answers to such a question. Here is just one of them: 1 & 249.
You can multiply the number 18 by different numbers that are relatively prime, for example by different prime numbers.
The set of Real NumbersThe set of Imaginary Numbers
Lots of irrational numbers are used; some of the more commonly used ones are:Square roots of different numbersHigher roots (cubic roots, etc.) of different numbersThe number piThe number eResults of trigonometric calculations; for example, the sine or cosine of certain angles
It is calculated the same way as if there were an odd number of numbers:mean = sum of all the numbers ÷ how many numbers there areThe median however is calculated slightly differently. After the numbers have been sorted into order, then:If there is an odd number of numbersThe median is the middle one which is the ((number_of_numbers + 1)÷2)th one. eg if there are 15 numbers this is the ((15+1)÷2)th = 8th number.If there is an even number of numbersThe median is given by the mean of the middle two numbers. eg if there are 20 numbers, then the median is the mean of the (20÷2)th = 10th and the (20÷2+1)th = 11th numbers, ie the median is (10th number + 11th number)÷2
I believe it's accurate to say that there are an infinite number of subsetsof real numbers. Not only that, there could be an infinite number of subsetsthat have an infinite number of members.A few of them would be:the odd numbersthe even numbersthe even numbers between 10 and 20the even numbers between 10 and 22the even numbers between 10 and 24the even numbers between 10 and 26the integers greater than 137the numbers between 4.0 and 4.1 that have more than 2 decimal placesthe prime numbers greater than 68,597the integers containing at least one '6'the powers of '2'...etc.
You can get any whole number as the answer. That is because there are infinitely many numbers which you can divide and they will give rise to different numbers for the answers.
There is an infinite number of answers.
Well there could be a lot of different answers to this, it's just a number minus another number to equal sixteen. It could be 21-5 for example.
The average (arithmetic mean) is the sum of the values divided by the number of values.Example : 5, 9, 10Their sum is 5+9+10 = 24 and there are 3 numbersThe average is 24/3 = 8
