Given: Security Service Company:
1.4 1.8 1.6 1.7 1.5 1.5 1.7 1.6 1.5 1.6
Mean: 1.59
Standard Deviation: 0.014333

Other companies: 1.8 1.9 1.6 1.7 1.6 1.8 1.7 1.5 1.8 1.7
Mean: 1.71
Standard deviation: 0.014333

The coefficient of variation for security Service Company:

CV = (Standard Deviation/Mean) * 100.

= (0.14333/1.59) * 100

= 9.01%

The coefficient of variation for other companies:

CV = (Standard Deviation/Mean) * 100.

= (0.014333 / 1.71) * 100

= 8.38%

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.

Which graph represents the function y = 2x – 4? A coordinate plane with a line passing through (negative 4, 0) and (0, 2). A coo

VARVARA [1.3K]

Answer:

The third option: "A coordinate plane with a line passing through (0, negative 4) and (2, 0)."

Step-by-step explanation:

Use the equation defined by the function: y = 2x - 4 to check the (x, y) values they give you. If they both render true mathematical statements, those are indeed points on the plane that belong to the given line.

For the third case; the pairs (0,-4) and (2,0), both satisfy the equation of the line that is given.

For (0,-4): y = 2x - 4 becomes:

$(-4)=2(0)-4\\-4=0-4\\-4=-4$ which is a TRUE statement
