Answer:
5.34
Step-by-step explanation:
X + 12.66 = 18
-12.66 -12.66
X = 5.34
12 is a factor of 36 and of course 12, so
Answer: 12
Answer:
= 14X + 6
Step-by-step explanation:
You have to subtract 3.2 from 3.5 to get x. 0.3+ 3.2=2.5 so x=0.3
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%
