Answer:
Its volume for a sphere where radius is 3cm
The real volume is 113.04 cubic meter
4x +31 = 35
6x +39 = 45
35 + 45 = 80
I believe it would be 80
Answer:
50%
Step-by-step explanation:
''What is the probability that she selected the biased coin?”
When we have n possible outcomes of an event and all of them have the same probability of appearance, then in theory each possibility has a probability 1/n of being the result of the event.
In this case the event is choosing randomly a coin out of 2, so no matter what the biased coin is or the results we get when we toss it, the probability of choosing the biased coin is ½ = 0.5 or 50%.
