The more times you do a test, the more accurate the results will be.
Since there are only 2 options/sides the probability should be 1/2 for both heads and tails.
Her error was both mathematical (her experimental probability number didn't make sense) and her lack of sufficient testing.
Answer: x = 0 and x = 7
Step-by-step explanation:
9x^2 - 63x = 0.
We can factor out 9x from both terms on the left side:
9x(x - 7) = 0.
To be equal to 0, one of the terms has to be 0.
Therefore, either 9x = 0 or x - 7 = 0.
First, we solve the case where 9x = 0.
Then, x = 0.
Second, we solve the case where x - 7 = 0.
We add 7 to both sides:
So, x = 7
Answer:
