The only way i can think of working out this question is this:
t = time p = phone calls
insert what we know:-
93 = p + 50
make P on its own:-
take away 50 from each side
43 = p
switch (you don’t HAVE to do this) :-
p = 43
So, shivani has to route a total of 43 phone calls to spend a total of 93 minutes on the phone.
- 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.

Hey there,
Your question states: <span>These are 2-dimensional shapes. They are made of straight lines, and the shape is “closed” (all the lines connect).
</span><span>The correct answer would be Polygon. Polygons are the shapes with a </span> 2-dimensional shapes, and has straight lines.
