Answer:
The Geometric Mean of 4 and 12 is 6.9
Step-by-step explanation:
Given Numbers are 4 and 12
To find : Geometric mean of the given No.
The Geometric Mean is a type of average where we multiply the nos. together and then take a square root (for two nos), cube root (for three nos) etc.
Formula for Geometric Mean is given by,
![Geometric\,Mean\,of\,x_1\,,\,x_2\,,\,x_3..x_n=\sqrt[n]{x_1\times x_2\times x_3\times\,...\,\times x_n}](https://tex.z-dn.net/?f=Geometric%5C%2CMean%5C%2Cof%5C%2Cx_1%5C%2C%2C%5C%2Cx_2%5C%2C%2C%5C%2Cx_3..x_n%3D%5Csqrt%5Bn%5D%7Bx_1%5Ctimes%20x_2%5Ctimes%20x_3%5Ctimes%5C%2C...%5C%2C%5Ctimes%20x_n%7D)
⇒ Geometric Mean of 4 and 12 = 
= 
= 
= 6.92820323028
= 6.9
Therefore, The Geometric Mean of 4 and 12 is 6.9
Answer:
Deena drove:
585 miles/9 hrs
....which means
her average rate was:
65miles/hour
whereas
Kristen drove:
605 miles/11 hrs
....meaning
her average rate was:
55 miles/hour
Therefore, Deena drove at a faster rate than Kristen

Answer:
Step-by-step explanation:
2.25m + 2(2.25m) + 90 cm =
2.25m + 4.50m + 90 cm
6.75m + 90 cm
1 cm = 0.01m...so 90 cm = 90 * 0.01 = 0.9m
6.75m + 0.9m = 7.65m <===

Answer:
x = 2
Step-by-step explanation:
-5(x + 2) = -20
-5x - 10 = -20
-5x = -20 + 10
-5x = -10
x = -10/-5
x = 2
