Answer:
Answer : A. 7 to 6
A soccer team won 7 of its 13 game
Total games played by soccer team = 13
Games won by the team = 7
Games lost = total games played - games won
So games lost = 13 - 7 = 6
Now we find the ratio of win to losses
game won = 7
games lost = 6
So the ratio of won to losses is 7 to 6
Step-by-step explanation:
Answer: 180/540
Simplified term would be 1/3
The answer is b
0.62068966 or 18/29 depending on how you want to set it up.
Answer:
Systolic on right

Systolic on left

So for this case we have more variation for the data of systolic on left compared to the data systolic on right but the difference is not big since 0.170-0.147 = 0.023.
Step-by-step explanation:
Assuming the following data:
Systolic (#'s on right) Diastolic (#'s on left)
117; 80
126; 77
158; 76
96; 51
157; 90
122; 89
116; 60
134; 64
127; 72
122; 83
The coefficient of variation is defined as " a statistical measure of the dispersion of data points in a data series around the mean" and is defined as:

And the best estimator is 
Systolic on right
We can calculate the mean and deviation with the following formulas:
[te]\bar x = \frac{\sum_{i=1}^n X_i}{n}[/tex]

For this case we have the following values:

So then the coeffcient of variation is given by:

Systolic on left
For this case we have the following values:

So then the coeffcient of variation is given by:

So for this case we have more variation for the data of systolic on left compared to the data systolic on right but the difference is not big since 0.170-0.147 = 0.023.
