Show one way to count from 82 to 512

Since they both end in 2 you could add 2 and then eventually get 512. Or you could do 512-82 and get 430 so then you could do 430 plus 82 is 512.

Arithmetic average of real nonnegative numbers is always smaller than or equal to geometric average. Group of answer choices Tru

noname [10]

Answer:

False

Step-by-step explanation:

Actually, the arithmetic average (or mean) is always greater or equal than the geometric average. This is known as the Arithmetic-Geometric inequality (AM inequality). Let a,b be two real numbers, then the AM inequality states that

$\frac{a+b}{2}\geq \sqrt{ab}$

To see that the given statement is false, consider a=1, b=3. The arithmetic mean is equal to (1+3)/2=2, and the geometric mean is equal to $\sqrt{1\cdot 3}=\sqrt{3}$ but $2>\sqrt{3}$ , contrary to the statement (arithmetic>geometric in this case).
