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 ...

Describe the possible solution sets of the (linear) equation ax = b. Identify the property: (x + 3) - 2 = (3 + x) - 2. (a) commutative (b) associative (c) distributive For all real numbers b and c such that the product of c and 3 is b,...
The sample solution, ObservableCollectionTest, contains a class named CustomerList, which inherits from ObservableCollection (seeFigure 1). As you might imagine, the CustomerList class exposes an ObservableCollection instance containing Customer objects. If you examine the code, however, you'll see that...
