Find the mean median and mode of the data set round to the nearest tenth 12 23 17 20 14 14 18 16 17 18 18 me find the mean median and mode !

For the given data set,

12,23,17,20,14,14,18,16,17,18,18

We have to determine the mean, median and mode.

Mean is calculated by the " sum of all the observations divided by the total number of observations".

First of all, let us arrange the numbers in ascending order.

12, 14, 14, 16, 17, 17, 18, 18, 18, 20, 23

Mean =

Mean =

Mean = 17

So, the mean of the data set is 17.

The mode of a set of numbers is the one that occurs most often.

Since, we observe that '18' is a number among the data set which occurs often.

Therefore, mode of the data set is 18.

Now, we will calculate median.

Since there are 11 terms. Since 11 is an odd number.

Median = th observation

=

= 6th observation

From the arranged data set, the 6th observation is 17.

So, the median of the data set is 17.

Hence, Mean = 17

Mode = 18

Median = 17

step-by-step explanation:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
