4/5*12/5
4*12=48, 5*5=25
so, 4/5*12/5=48/25
and 48/25=1 23/25
- Ana has the greater median
- Ana also has the greater mean.
Averagely, Ana practiced for a greater amount of time each day.
<h3>What is the Mean and Median of a Data Set?</h3>
- Mean = sum of data points / number of data points.
- Median = center/middle of the data distribution.
Mean for ana= (20 + 20 + 30 + 60 + 60 + 60 + 70 + 70 + 100 + 100 + 100 + 115 + 115 + 115)/14 = 69.6
Mean for tara= (20 + 20 + 30 + 30 + 45 + 45 + 45 + 70 + 70 + 70 + 75 + 90 + 90 + 120)/14 = 58.6
Median for ana= 70
Median for tara= (45 + 70)/2 = 57.5
Ana has the greater median and also has the greater mean.
Averagely, we can conclude that ana practiced for a greater amount of time each day.

Answer:
Step-by-step explanation:
You have the equation .
Then, to solve for the variable from the equation you need:
Make the subtraction of the right side of the equation:
(As the denominators are 1 and , the least common denominator is )
Multiply to both sides:
Add to both sides:
And finally divide both sides by :
