Find the median of the following data:<br>
10,16, 15, 14, 8, 21, 10, 5, 19, 18, 4, 5, 16, 12, 10,9

Answer:
The median is 11.
Step-by-step explanation:
First arrange the data in ascending order:
4, 5, 5, 8, 9 , 10, 10, 10, 12, 14, 15, 16, 16, 18, 19, 21
There are 16 numbers so the median is the mean of the middle 2 numbers in the list. That is the mean of the 8th and ninth number.
Median = 10 + 12 / 2
= 11.
Answer:
525 children attended the concert.
Step-by-step explanation:
Given that:
Total number of people who attended concert = 2500
Adult females = 47%
Adult males = 32%
Percent of children = (100-47-32)% = 21%
Number of children = 21% of people who attended
Number of children =
Number of children = 0.21*2500 = 525
Hence,
525 children attended the concert.
The answer is 1,-2 because I googled it
A) In terms of the areas of the circles:
.. walkway area = π*(11 m)^2 -π*(9 m)^2 = π*(121 -81) m^2 = 40π m^2
In terms of the length of the walk and its width:
.. walkway area = 2*π*(10 m)*(2 m) = 40π m^2
b) The approximate area is
.. 40*3.14 m^2 = 125.6 m^2
