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:
0.249874
Step-by-step explanation:
After every 4 digits, n squared is divisible by 8 so we have 1989/4= 497 numbers divisible by 4 after squaring
probability n=497/1989= 0.249874
Probability n=0.249874
Answer:
ok good Step 1
Write your problem.
537.95 x 9.5% = ?
Step 2
Convert the % to a decimal:
9.5% to 0.095
Step 3
Rewrite the problem with decimal replacing the percentage.
Now the problem looks like this:
537.95 x 0.095 = 51.11
This problem gives the amount of the tax.
Step 4
Add the original price with the tax amount:
537.95 + 51.11 = $589.06 (total cost)
