Answer:
0.0313
Step-by-step explanation:
Given that in the shipment of 71 vials, only 13 do not have hairline cracks
Probability of not having a hairline cracks = 
If you randomly select 2 vials from the shipment
(Probability of not having a hairline cracks)' =
= 
what is the probability that none of the 2 vials have hairline cracks.
i.e 
= 0.183 × 0.171
= 0.0313
Hence, the probability that none of the 2 vials have hairline cracks = 0.0313
Answer:
C
Step-by-step explanation:
Answer:
7 -5i
Step-by-step explanation:
The additive inverse is the number we add to make it equal to zero
-7+5i + x = 0
the real part
-7 + x = 0
x = 7
The imaginary part
5i+x = 0
x = -5i
The complex x is
7 -5i
Notice it is the opposite of the number
- (-7+5i)
7-5i
