The mean is (4+6+8+17+x)/5=(35+x)/5.There are three possibilities for the median: it is either 6,8, or x. Let's start with 6. (35+x)/5=6 has solution x=-5, and the sequence is -5,4,6,8,17, which does have median 6, so this is a valid solution.Now let the ...
In this lesson, let us learn all about what are real numbers, the subsets of real numbers along with real numbers examples.What are Real Numbers?Any number that we can think of, except complex numbers, is a real number. For example, 3, 0, 1.5, 3/2, √5, and so on are real ...
which has median 8. This case is therefore again not valid. Hence the only possible vaue of x is (A)−5.结果一 题目 What is the sum of all real numbers x for which the median of the numbers 4, 6, 8, 17, and x is equal to the mean of those five numbers?( )A.−5B....
Is 0 a real number? What are imaginary numbers? Find all real numbers x such that (log_2(x))^2 = 5 log_2 (x) + 6. (a) Find all real numbers x such that Find all real numbers x such that: (x2 - x - 2)4 + (2x + 1)4 = (x2 + x - 1)4. ...

A real number is any positive or negative number available within the entire mathematical range of numbers. Real numbers include whole numbers, rational numbers, irrational numbers and virtually any type of number that is not an imaginary number or that can’t be computed or processed logically. ...
What is a real number?Imaginary Numbers:Imaginary numbers are also called complex numbers. When imaginary numbers are squared, the result is a negative number. Imaginary numbers are used in certain calculations, such as quadratic equations. They are the result of a real number multiplied by i, ...

Beginning with the intuitive notion of counting, the book progresses step-by-step to the real numbers. Each sort of number is defined in terms of a simpler kind by developing an equivalence relation on a previous idea. We find the finite sets' equivalence classes are the natural numbers. ...
