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.
Step-by-step explanation:
Answer:
The sequence is a function as for any value of n we can not get more than one different value.
Step-by-step explanation:
Tilly starts by running 1 mile in the first week and tripling the number of miles each week.
Now, the number of miles Tilly will run can be modeled by the sequence , where n is the number of weeks since she began her program.
Therefore, in the second week she runs 3 miles, in the third week she runs 9 miles and so on.
Therefore, the sequence is a function as for any value of n we can not get more than one different value. (Answer)
