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%
a) C = 40 + 30t
b) 280 = 40 + 30t
30t = 240
t = 8

Answer:
11
Step-by-step explanation:
18 1/2 + (-7 4/8)
Simplify the fraction
18 1/2 + (-7 1/2)
Subtract the whole numbers
18-7 = 11
Subtract the fractions
1/2 -1/2 =0
