value per house and number of houses
150,000, 2
220,000, 4
490,000, 3
540,000, 2
800,000, 5
975,000, 2
That values of several houses on Mango Street are displayed on the table. What is the median value of these houses. The answer is 515,000 please explain how.!!
To find the median value of these houses, we first need to rearrange the values in ascending order:
150,000
220,000
490,000
540,000
800,000
975,000
Since there are a total of 18 numbers, the median will be the average of the 9th and 10th numbers when they are in ascending order. In this case, the 9th and 10th numbers are 490,000 and 540,000.
Therefore, the median value of these houses is (490,000 + 540,000) / 2 = 515,000.
how is there 18 numbers
I apologize for the mistake in my previous response. Let's correct that.
We have a total of 2 + 4 + 3 + 2 + 5 + 2 = 18 houses in total. Let's arrange the values in ascending order again:
150,000
220,000
490,000
540,000
800,000
975,000
Since we have an even number of values (18), the median will be the average of the 9th and 10th values when they are in ascending order. In this case, the 9th and 10th values are 490,000 and 540,000.
Therefore, the median value of these houses is (490,000 + 540,000) / 2 = 515,000.
