RSM can send 4 of its 18 teachers into a conference in 3060 ways.
Combinations are the various ways in which objects from a given set may be selected. Normally it is done without replacement, to form the subsets. Combinations are a way to find out the total outcomes of an event where the order of the outcomes does not matter.
Thus the Combination is the different selections of a given number of objects taken some or all at a time. For example, if we have two alphabets A and B, then there is only one way to select two items, we select both of them. For Combinations, k elements are selected from a set of n objects to produce subsets without bothering about ordering. Here Combinations BA and AB will be no longer distinct selections. Thus by eliminating such cases we get only 10 different possible groups, which are AB, AC, AD, AE, BC, BD, BE, CD, CE, and DE.
Thus RSM can send 4 of its 18 teachers into a conference = 18C
18C = 3060 ways
Thus RSM can send 4 of its 18 teachers into a conference in 3060 ways

Answer:
D. Lengths 1 foot, 12 inches, and 25 inches
Step-by-step explanation:
When looking for side lengths of a triangle, there are three factors we need to look into, take a right triangle for example.
There are two small sides and one long side of a right triangle, to answer the question, we need to find two numbers that when added together (two short sides of triangle), equal to less than the long side of the triangle.
A. would be wrong because 3 feet and 4 feet added have a greater amount then 5 feet.
B. would be incorrect because 5 inches and 12 inches (1 foot) equal way more than 13 inches (1 foot and 1 inch).
C. would be wrong because 1 foot (12 inches) and 1 inch equal way more than 1 inch.
D. would be correct because 1 foot (12 inches) and 12 inches equal less than 25 inches.
1 foot + 12 inches = 24 inches
24 inches < 25 inches.
D is the answer.
