Answer:
We use Baye's theorem: P(A)P(B|A) = P(B)P(A|B)
with (A) being defective and
(B) marked as defective
we have to find P(B) = P(A).P(B|A) + P(¬A)P(B|¬A). .......eq(2)
Since P(A) = 0.1 and P(B|A)=0.9,
P(¬A) = 1 - P(A) = 1 - 0.1 = 0.9
and
P(B|A¬) = 1 - P(¬B|¬A) = 1 - 0.85 = 0.15
put these values in eq(2)
P(B) = (0.1 × 0.9) + (0.9 × 0.15)
= 0.225 put this in eq(1) and solve for P(B)
P(B) = 0.4
Answer:
40.82 is the surface area of this solid.
She uses 4/3 (1 1/3) pint of hair gel in 4 days
Repeated fractions are written with 9's in the denominator.
0.136 = 136/1000
0.136 repeated = 136/999
2.00+9.00+6.00+3.00+5.00+4.00+8.00-1.00-2.00= $34.00$1.44 - 34.00
41.44 - 34.00 = 7.44
The difference is $7.44, therefore the amount on the register is not reasonable.
