Answer:
Step-by-step explanation:
The given equation is 
.
We take logarithm of both sides to base 2 to get:
Apply the power rule of logarithms to get:
We now apply the change of base formula:
To the nearest thousandth,
Answer: The average age is 7.1 years.
This problem is an example of when we need to take a weighted average. We simply can't just find the average of 5 and 8, because there are different children of each each.
To start, lets multiply the total number of children by their individual ages.
6 x 5 = 30 years
14 x 8 = 112 years
There are 142 years among the 20 years, so divide 142 by 20. This gives us an average age of 7.1 years.
Answer:
13:117 = 1:3
5:125 = 1:5
8:128 = 1:4
12:48 = 1:2
Step-by-step explanation:
117/13 = 9
√9 = 3
125/5 = 25
√25 = 5
128/8 = 16
√16 = 4
48/12 = 4
√4 = 2
