A manager wants to determine if an employee training program has increased her employees’ customer satisfaction ratings. She ran

domly selects 10 of the participating employees and compares their customer satisfaction ratings before and after the training. The results are shown in the table.
Employee Before After Difference
1 4.2 4.3 0.1
2 3.7 3.6 Negative 0.1
3 2.9 3 0.1
4 3.2 3.3 0.1
5 3.1 3 Negative 0.1
6 4.1 4.2 0.1
7 2.8 2.9 0.1
8 2.8 2.7 Negative 0.1
9 4 4.2 0.2
10 3.6 3.7 0.1
How can the values in the Difference row of the table be interpreted?

A. A negative difference means that the program was effective, and any positive differences can be ignored.
B. A positive difference means that the employee’s rating increased after the program, and a negative difference means that the employee’s rating decreased after the program.
C. A positive difference means that the employee’s rating decreased after the program, and a negative difference means that the employee’s rating increased after the program.
D. A positive difference means that the program was effective, and any negative differences can be ignored.

Given a regular decagon, find the measures of the angles formed by (
Sonja [21]
A decagon has 10 sides (think decade and decathlon). From the center of the decagon we draw the radii and in doing so we take the area of the decagon and divide it into 10 congruent Triangles.

The angles around the center add up to 360 because they form a circle and since there are 10, they each measure 36 degrees. So the answer to the first part (the angle between the radii) is 36 degrees.

Each of these triangles has two equal sides (both radii) so is Isosceles. That means that the base angles are congruent. So the two angles that are left in each triangle must measure the same. Since the angles in a triangle add up to 180 degrees, we know that the two remaining angles are together equal to 180-36=144 degrees. Since they are equal in measure they each measure 72 degrees.

Thus the answer to the second part, trhe measure of the angle between a radius and the side of the polygon is 72 degrees.

The value of x is 1.25 or 1 1/4

Explanation
==============================
275x=500-125x 
Move variable to the left side and change its sign
275x+125x=500
Collect the like terms
275x+125x=500 =====> 400x=500
Divide both sides of the equation by 400
400x/400=500 =======> x=5/4 which is the same as 1 1/4 or 1.25
Hope this helps : )

Oduvanchick [21]
Step 1: -3(x+2y=3)
Step 2: -3x-6y=-9
Step 3: 3x cancels out with -3x
Step 4: add 2y and -2y, and add 3 and 5
Step 5: the answer is NO SOLUTION or INFINITE SOLUTION
