A lie-detector works correctly with 80% probability when the person is lying, and with 90% probability when the person is not. A
muminat

Answer:

the time percentage is 17%

Step-by-step explanation:

The computation of the time percenatge in the case when the detector lie and done with the mistake is as follows:

L denotes the event  in which a person is lying.

NL denotes the event in which a person is not lying.

C denotes the event in which that lie detector works correctly

NC denotes the event in which  lie detector is not working correctly

Now

P(C|L) =0.8

And,

P(NC|L) is

=1 - .8

= 0.2

P(C|NL) =0.9

P(NC|NL) is

= 1 -.9

=.1

P(L) = 0.7

P(NL) is

= 1 - .7

= .3

Now

P(NC) =P(NC|L) × P(L) + P(NC|NL) × P(NL)

=. 2 × .7 + .1 ×.3

=. 14+.03

= 0.17

Hence, the time percentage is 17%

Solve for x: 3|x − 3| + 2 = 14
vaieri [72.5K]

Answer:

x = 7                      x = -1

Step-by-step explanation:

3|x − 3| + 2 = 14

Subtract 2 from each side

3|x − 3| + 2 -2= 14-2

3|x − 3|  = 12

Divide by 3

3|x − 3| /3 = 12/3

|x − 3| = 4

Now the absolute value has a positive and negative solution.

x-3 = 4      x-3 = -4

Add 3 to each side

x-3+3 = 4+3      x-3+3 = -4+3

x = 7                      x = -1
