If I where you I would think of the value of a triangle then calcualate the answer, I would tell you but I don’t really know hope that helped
Answer: A plane has two dimensions because it is a flat surface that has length and width but no depth.
Let's imagine that we turn the machine on 100 times. (this will make the percent conversion easier)
the chance that works in the morning is 50% of 100 so it will work 50 times.
the chance that it will then continue for the rest of the day is 15% so 15%*50 (the number of times it worked), which is 7.5 times.
our times actually represented percent, so the answer is : 7.5%!
