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%.
Answer:
logₐ(8) = 0.903
Step-by-step explanation:
logₐ(8) = logₐ(2)³
= 3logₐ(2) [Since, ]
= 3(0.301) [Given → log(2) = 0.301]
= 0.903
Therefore, logₐ(8) = 0.903 is the answer.
