Acompany's management is worried about employee drug use and is instituting a policy of mandatory drug tests. if an employee is a drug user, there is an 85% chance that he or she will test positive. if the employee is not a drug user, there is a 95% chance that he or she will test negative. individuals who test positive are fired. we do not know the fraction of employees who are drug users. we do know, however, that 10% of all employees tested positive.
a) what fraction of employees are drug users?
b) of those who test positive, what fraction are in fact not drug users?

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
