Step-by-step explanation:
1.75n = 7 ( to isolate n divide both sides by 1.75 )
n = = 4
For this case, the first thing we must do is define variables.
We have then:
x: number of minutes
y: final temperature
We write then the equation that models the problem:
For y = 20 we have:
Clearing x:

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
