The list shows the number of stories in the 11 tallest buildings
in Springfield. Find the median and mode of the data.
40, 38, 40, 37, 33, 30, 20, 24, 21, 17, 19

The median and mode of the given data is 30 and 32 respectively.

Step-by-step explanation:

Given,

The number of stories in 11 buildings are 17,19,20,21,24,30,33,37,38,40,40

To find the median and mode of the data.

Formula

Mean = sum of the data ÷ number of terms

If the number of term is odd, the median = th term

Mode = 3 Median - 2 mean

Now,

Mean = (17+19+20+21+24+30+33+37+38+40+40)÷11 = 29

Median = th term = 6th term = 30

Hence,

Mode = 3×30-2×29

= 90-58 = 32

4 + 5 7/9= 9 7/9

step-by-step explanation:

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
