Solve 0.05p-0.02(5-2p)=0.05(p-2)-0.12
Montano1993 [528]
0.05p-0.02(5-2p)=0.05(p-2)-0.12 

0.05p-0.02(5-2p)=0.05(p-2)-0.12:p 


0.05p-0.1+0.04p=0.05p-0.1-0.12
 
  |Expand \ the \ equation| 

0.09p-0.1=0.05p-0.1-0.12
 
 

0.09p-0.1=0.05p-0.22 


0.09p-0.1-0.05p=-0.22
 

  |Subtract \ 0.05p \ from \ both \ sides| 


0.04p-0.1=-0.22
 
 


0.04p=-0.22+0.1
 
  |Add \ 0.1 \ to \ both \ sides| 


0.04p=-0.12
 
 

0.04p/0.04=-0.12/0.04
  |Divide \ both \ sides \ by \ 0.04| 

p=-3

diamong [38]

Answer:

0.070

Step-by-step explanation:

Y = number on trial

Y has a negative binomial distribution

r = 3

P = 30% = 0.3 probability of positive indication.

P(Y = 11) probability of 11 employees that must be tested to get 3 positives

Y-1Cr-1*p^r*q^(y-r)

Y-1 = 11-1 = 10

r-1 = 3 -1 = 2

10C2 x 0.3³x0.7⁸

45x0.027x0.05764801

= 0.070

This is the probability that 11 employees must be tested to get 3 positives.
