Answer:
2/3
Step-by-step explanation:
6/9=8/12=2/3
........
The value of nth term is calculated by the equation,
an = (a1) x r^(n - 1)
Using this equation to find for the common ratio,
-8192 = 8 x r^(6 - 1)
The value or r is -4. Using the same equation to find for the 12th term,
a12 = 8 x (-4)^(12 - 1)
a12 = -33554432
The answer is 3.2. you have to find the mean subtract then find the mean again
Answer: A. 51%
Step-by-step explanation:
Area of circle = , where r = radius of the circle.
In the figure below, we have the complete question.
According to that,
Radius of outer circle = 7ft
Radius of inner circle = 5ft
The probability that the thumbtack will be placed on the inner circle
[π is canceled from numerator and denominator
in percent,
So, the probability that the thumbtack will be placed on the inner circle = 51%
Hence, the correct option is A. 51%.
