Answer:
The pair that performs second are Orville and Nancy.
Step-by-step explanation:
Since Jack and Leslie are partners and that they appear before Kelly, it is safe to assume that this pair may come first beforehand in which Orville also comes on before Kelly. Nancy also appears before Leslie and since each pair has a female and a male, it is safe to assume that Orville and Nancy perform second while Jack and Leslie perform first and Kelly and Marty perform last.
This is a non replacement question, so each letter decreases by 1.
No vowels
The question actually starts right here. The preamble tells us that we can only use letters, no numbers, and no symbols. We are not asked to do anything. The first question makes no mention of there being anything special about m. It can be there or it most likely is not. This part of the problem is the first part.
First Part
I'm not going to deal with y. I will declare it to be a consonant.
There are 5 vowels. None of them can be chosen.
21 letters remain (including the m since it has not been limited in any way yet).
21 * 20 * 19 * 18 * 17
================
26 * 25 * 24 * 23 * 22
2441880 / 7893600
0.30934
Note: If your calculator has nPr on it, you can enter 21 nPr 5 to eliminate all the typing.
Second Part
No vowels and the first letter MUST be m
1 * 20 * 19 * 18 * 17/( 26 * 25 * 24 * 23 * 22)
116200/7893600 = 0.01473
Vowels and the first letter m.
1 * 25 * 24 * 23 * 22/ 7893600 = 0.03846
There are 4 rules for congruent triangles:
SSS-->This means side,side,side and to prove triangles are congruent with this rule, all the sides will be the same on both triangles.
SAS-->This means side,angle,side and to prove triangles are congruent, you must have 2 sides and an angle the same on both triangles, but the angle MUST be in between the 2 sides.
ASA-->This means angle, side, angle and to prove triangles are congruent with this rule, you must have two angles and a side the same, but the side MUST be in between the two angles.
RHS-->This means right angle, hypotenuse, side and to prove triangles are congruent with this rule, you must have a right angle in both triangles, and have an equal hypotenuse and side.
Hope this helps:)
