The mean is 76.4.
The median is 72.
Mean: 70 + 72 + 99 + 72 + 69 = 382
382 divided by 5 is 76.4.
Median : Order the data set
69, 70, 72, 72, 99
The median is a better description because in the data set there is an outlier (99).
Hope this helped! :D

Answer:
rs 30 per litre.
Step-by-step explanation:
We have 90 litres left after the leakage and we paid rs 2500 for it. To gain a 8% profit we have to sell 90 litres for 2500 * 1.08 = rs 2700.
So each litre has to be sold for rs 2700 / 90 = rs 30.
Answer:
7.
Step-by-step explanation:
The equation of a circle is
(x - h)² + (y - k)² = r²
Where
(h, k) is the center and r is the radius, so we only need to work with r.
The expression states that
r² = 49 or the radius squared is equal to 49. So solve for r to find the radius.
r² = 49
Take the square root.
r = 7
The radius of the equation is 7.
