Answer:
building a aroung 50.34 feet
Answer:
about 34.9%
Step-by-step explanation:
The probability of not making a marking error is 0.9. The probability of doing that 10 times independently is 0.9^10 ≈ 0.34868 ≈ 34.9%.
You basically make an equation out of this and set the two expressions equal to each other.
Let x equal the number of hours where the snowfall will be equal in both towns.
In town one, the amount of snowfall can be written as 2+6x. In town two, the amount of snowfall can be written as 7+3x.
So to find when they will be equal, set them equal and solve:
2+6x=7+3x
3x=5
x=5/3 or 1 2/3 hours. In minutes, this is 100 minutes.
One is 5% of 20 I believe
