The surface area of Spaceship Earth is: 7850 m^2
Step-by-step explanation:
Given
Diameter of spherical structure = d = 50 meters
As the attraction is in the form of a sphere, its radius will be used to find the surface area.

The formula for surface area of sphere is:

Answer:unpredictable
Step-by-step explanation:
They don't seem equivalent, the first set yields 4+3xy and 7xy. The second set yields 10-(6/y) and 4/y. R u sure u typed in the question correctly?
Answer: 0.9990
Step-by-step explanation:
Given : The number of bits in a string = 10
The value taken by a bit is either 0 or 1.
Therefore, the probability that the bit is zero = 
Binomial probability distribution formula :-
, where P(x) is the probability of getting success in x trials , n is the total number of success and p is the probability of getting success in each trial.
Now, the probability that you picked a string with at least one zero is given by :-

Hence, the probability that you picked a string with at least one zero = 0.9990
