Answer:
D
Step-by-step explanation:
First, it is important to understand the terms used in the problem.
The Arithmetic Mean: (this is the mean we are used to seeing)
(n= number of variables, in this case n=3)
To Find the Geometric Mean of n #'s:
(n= number of variables, in this case n=2)
So, using this information we can find the geometric mean of 6,7 by plugging them into the equation as "a" and "b". n=2 (when n=2 a square root can be used)
So the answer in this case is A.
Answer:
10/12
Step-by-step explanation:
5 2
----- * ----- =
6 2
5 * 2 = 10
6 * 2 = 12
The fraction becomes 10/12

[ Explanation ]
- Factor x3 - 7 · 2 - 5x + 25 By Grouping
--------------------------------------------
- Add Similar Elements: 3x - 5x = -2x
-2x - 7 · 2x + 35
- Multiply Numbers: 7 · 2 = 14
-2x - 14x + 35
- Add Similar Elements: -2x - 14x = -16x
-16x + 35
3p + 2s + b...when p = 39.99 and s = 17.89 and b = 49
3(39.99) + 2(17.89) + 49 = 204.75 <==
