Given:
The data set is
21, 16, 30, 15, 16, 18, 10, 24, 26, 20, 19, 24, 24, 25, 23
10, 15, 16, 16, 18, 19, 20, 21, 23, 24, 24, 24, 25, 26, 30
To find:
The range, average and median for the given data set.
Solution:
Arrange the data set in ascending order.
10, 15, 16, 16, 18, 19, 20, 21, 23, 24, 24, 24, 25, 26, 30
(1)
Range = Maximum value - Minimum value
= 30 - 10
= 20
Therefore, the range of the given data set is 20. All the options are incorrect.
(2)
Therefore, the average score is about 20.73. All the options are incorrect.
(3)
Number of observations = 15, which is odd.
In the arranged data set 8th term is 21.
Therefore, the correct option is b.
M=72 that’s the best I can give you lol not sure if that helps any
Answer:
l = 6 + 2a - 1
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = lw ( l is the length and w the width )
given A = 18 + 6a² - 3a and w = 3a , then
3aw = 18 + 6a² - 3a ( divide each term by 3a )
w = +
-
= 6
+ 2a - 1
