The probability that the 5 will end up as a 10s digit (not a 1s digit) is 1/2. Thus, about half of the experiments are expected to result in a 2-digit number that begins with 5.
If the experiment is performed 10 times, the expected number of times a 2-digit number begins with 5 is 5.
The area is 452.39
Hint : If you know the radius of a circle , you can use it to find the area of what that circle . Just plug that value into the formula for the area of a circle and solve .
I hope that's help !

Answer:
Below are explanations!
Step-by-step explanation:
6) 5^4/5^2 means the ^4 and ^2 needs to subtract from the 5s. This results in 5^2, which equals 25.
7) The 9 as the denominator will cross with the first nine above. This leaves as follows: 9^3 x 9^2 x 9^6 (I don't know if it is a 6 or 0). You may solve from there. Just add all the exponents up.
8)^-6 will be multiplied by ^6, which is ^-36. Therefore, the answer is 5^-36.
