Answer: c = 4 + (8/3)d

Step-by-step explanation: Let's isolate c:

What are the mean absolute deviation and population standard deviation of this data set? Round to the nearest tenth if necessary
tekilochka [14]

Answer:

For a data set of N elements:

{x₁, x₂, ..., xₙ}

The mean is:

M = \frac{x_1 + x_2 + ... + x_n}{N}

The mean absolute deviation is:

MAD = \frac{|x_1 - M| + ... + |x_n - M|}{N}

And the population standard deviation is:

PSD = \frac{\sqrt{|x_1 - M|^2 + ... + |x_n - M|^2} }{\sqrt{N}}

In this case, our set has 5 elements, and the set is:

{2, 4, 6, 9, 14}

The mean of this set is:

M = \frac{2 + 4 + 6 + 9 + 14}{5} = 7

The mean absolute deviation is:

MAD = \frac{|2 - 7| + |4 - 7| + |6 - 7|+ |9 - 7| + |14 - 7| }{5} = 3.6

And the population standard deviation is:

PSD =  \sqrt{\frac{|2 - 7|^2 + |4 - 7|^2 + |6 - 7|^2+ |9 - 7|^2 + |14 - 7|^2 }{5}} = 4.2

Yolanda spends 82/3 hours per month playing soccer. Approximately how many hours does she play soccer in a year?
Vesnalui [34]
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.

Leena knits 10 rows in 12 min. At this pace, how long will it take her to knit the next 25 rows?
tatiyna
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!
