Answer:
I took them a total of 5 hours
Step-by-step explanation:
First you multiply 65 by 2 because of the first two hours
Then you subtract 130 out of 364 to get 234, those were the first two hours
The next hours you simply divide 234/78, which is 3
3 + 2 = 5 hours
Answer:
1. No, 2. 46, 3. The amount of tails flips would be more than the amount of heads flips.
Step-by-step explanation:
1 is no because .77 and .23 are not equal to .5, so her prediction was wrong. 2 is 46 because if you double both the numbers (to get a total of 200 flips), you would get 154 tails and 46 heads. 3 is more tails than heads because that is what we have observed.
I don’t even know :( sorry
