Replace x in the equations and see which one gets the matching y :

-5(0) = 0 +1 = 1

-5(1) = -5 + 1 = -4

-5(-1) = 5 +6 = 6

The first equation works.

(x-4)*(x-9)=0 what is x
Strike441 [17]

Answer:

x either equals to 4 of 9 so you can write it like x=4, 9

Step-by-step explanation:

Start by simplifying each sides of the equation.

x^2-13x+36=0

Then factor the left side of the equation.

(x-4)(x-9)=0

Set factors equal to 0

x-4=0 or x-9=0

x=4 or x=9

dezoksy [38]
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.
