Step-by-step explanation: You plug in those numbers for X
It is false that city parks are part of the natural environment.
Since we are the ones who built them, they couldn't have been created by nature.
-3/5 becuase 1/10 minus 2/5 is -3/5
Answer:
35
Step-by-step explanation:
If the median of data (arranged in ascending order) 31,33,35,x,x+10,48,48,50 is 40,then find value of x.
Solution:
The median of a data is the middle number after the numbers from the data have been arranged either from least to greatest or from greatest to least. For an even number of data, the median is the average of the middle two numbers.
The data arranged in ascending order is:
31,33,35,x,x+10,48,48,50
SInce the data has an even number (8), the median is the average of the middle two numbers.
Median = average of x and x + 10
[x + (x + 10)] / 2 = median
[x + (x + 10)] / 2 = 40
x + x + 10 = 80
2x + 10 = 80
2x = 70
x = 70/2
x = 35
