Answer:
67 million square miles
Step-by-step explanation:
The area of a sphere is given by ...
A = 4πr²
So the area of the Earth is approximately ...
A = 4π(4000 mi)² ≈ 2.01×10^8 mi²
The area of the 1/3 that is not covered by water is approximately ...
(2.01×10^2 mi²)/3 = 6.7×10^7 mi²
The land area is estimated to be about 67 million square miles.
Answer:
x=i√33−3,−i√33−3
hope this helps :)
Step-by-step explanation:
Subtract 5 from both sides of the equation.
(x+3)2=−28−
5 Subtract 5 from −28.
(x+3)2=−33
Take the square root of both sides of the equation to eliminate the exponent on the left side.
x+3=±√−33
Simplify the right side of the equation.
x+3=±i√33
The complete solution is the result of both the positive and negative portions of the solution.
x=i√33−3,− i√33 −3
Answer: The probability that his friend doesn't make a shot until his 5 th attempt is 0.00128.
Step-by-step explanation:
Since we have given that
Probability of making his shot = 80%
Probability of missing his shot = 20%
We need to find the probability that his friend doesn't make a shot until his 5th attempt.
So, our required probability would be
Hence, the probability that his friend doesn't make a shot until his 5 th attempt is 0.00128.
