Find the median and mean of the data wich reflects the best measure of the center

mean= 16.9

Median= 14

Step-by-step explanation:

Mean= sum of data set/ number of data set

= 118/7 =16.9

Median- the middle number of a data set, to reflect the best measure of the centre, the data set should be arranged in an ascending order

12, 13, 13, 14, 21, 22,23 14 is the median

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21
