Answer:
1. Area = Base * Height
2. 144x = 4x * 4x
3. 144x = 16(x^2)
4. 9x = x^2
5. x = 9
Step-by-step explanation:
Answer:
For a data set of N elements:
{x₁, x₂, ..., xₙ}
The mean is:

The mean absolute deviation is:

And the population standard deviation is:

In this case, our set has 5 elements, and the set is:
{2, 4, 6, 9, 14}
The mean of this set is:

The mean absolute deviation is:

And the population standard deviation is:

328 because 82/3 multiplied by 12 is 328 and you do that because there's 12 months in a year and if you spend 82/3 hours per month playing soccer than you would multiply that by 12 which gives you 328 hours.
For 10 rows, she takes = 12 min.
So, for 1 row, she'll take = 12/10
Now, for 15 rows, it would be: 12/10 * 25 = 12/2 * 5 = 60/2 = 30
So, Your Final Answer would be 30 minutes
Hope this helps!
