Answer:

Step-by-step explanation:

12x - 2 + 20x - 10 = 180

Can someone help me find the median of this question please.
vodomira [7]

Answer:

median = 2.8 m

Step-by-step explanation:

the median is the middle value of the data set in ascending order.

If there is no exact middle value then it is the average of the values either side of the middle.

the stem- leaf diagram shows the data in ascending order from 1.6 to 4.5

there are 10 data values so no exact middle value.

the median lies between 2.7 and 2.9

median = (2.7 + 2.9) ÷ 2 = 5.6 ÷ 2 = 2.8 m
