What goes in goes out. This means none of the current is lost. So if 0.7amps+0.68amps+0.47amps = 1.85 amps comes in, then 1.85 amps goes out. So far we have 0.8 amps+0.55 amps going out= 1.35 amps. This means we need an additional 1.85-1.35amps going out= 0.5 amps for the third outgoing current. Cheers!
The probability that a student, chosen at random, does not study chemistry is 20/41.

What is Probability?</h3>
Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Here, Total number of student = 41
Student who does not study chemistry = 20
So, the probability = favorable outcome / total outcomes
P(not studying chemistry) = 20 / 41
Thus, The probability that a student, chosen at random, does not study chemistry is 20/41.

Step-by-step explanation:
The expression is:
![speed(minutes)=3\frac{km}{h} ^{minutes} \\\\speed(15minutes)=(3^{15})\frac{km}{4} =14348907\frac{km}{g}](https://tex.z-dn.net/?f=speed%28minutes%29%3D3%5Cfrac%7Bkm%7D%7Bh%7D%20%5E%7Bminutes%7D%20%5C%5C%5C%5Cspeed%2815minutes%29%3D%283%5E%7B15%7D%29%5Cfrac%7Bkm%7D%7B4%7D%20%3D14348907%5Cfrac%7Bkm%7D%7Bg%7D)
Why?
From the statement we know that the spaceship travels 3 times faster each minute that it traveled during the minute before, it can be expressed using an exponential function, its base will be the starting speed (during the first minute).
The expression will be:
![speed(minutes)=(3^{minutes})\frac{km}{h} \\\\speed(15minutes)=(3^{15})\frac{km}{h}=14348907\frac{km}{h}](https://tex.z-dn.net/?f=speed%28minutes%29%3D%283%5E%7Bminutes%7D%29%5Cfrac%7Bkm%7D%7Bh%7D%20%5C%5C%5C%5Cspeed%2815minutes%29%3D%283%5E%7B15%7D%29%5Cfrac%7Bkm%7D%7Bh%7D%3D14348907%5Cfrac%7Bkm%7D%7Bh%7D)
