4,11,6,9,23,34,6,9

what is the median for this set of numbers
a. 6
b.10
c.14
d.16

The Median is 9

Step-by-step explanation:

To calculate the median of a data set the first step is to sort the data from least to greatest

4,11,6,9,23,34,6,9

4, 6, 6, 9, 9, 11, 23, 34

The second step is to locate the central value. If the total amount of data is an even number then locate the two central data and the median will be the average of both. In this case we have 8 data. Then the central values will be the data number 4 and the data number 5

4, 6, 6,   [9, 9],   11, 23, 34

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
