Given:
Security Service Company:
1.3 1.7 1.6 1.4 1.5 1.5 1.7 1.6 1.4 1.5
Mean: 1.52
Standard Deviation: 0.131656

Other companies:
1.9 1.8 1.6 1.7 1.6 1.8 1.7 1.6 1.7 1.6
Mean: 1.7
Standard deviation: 0.105409

The coefficient of variation for security Service Company:
CV = (Standard Deviation/Mean) * 100.
= (0.131656/1.52) * 100
= 8.66%

The coefficient of variation for other companies:

CV = (Standard Deviation/Mean) * 100.
= (0.105409 / 1.7) * 100
= 6.20%

The limited data listed here show evidence of stealing by the security service company's employees because there is a significant difference in the variation.

What are the coordinates of the point obtained if the point A=(3,7) is rotated 180 degrees about the origin?
Yuliya22 [10]

Answer:

B. (-3, -7)

Step-by-step explanation:

Anytime you rotate a number 180° about the origin, the numbers in the coordinates become their opposites.

-3 is the opposite of 3 and -7 is the opposite of 7.

Therefore, your new coordinates are (-3, -7)

(x,y) becomes (-x,-y)
