Answer:
The highest observation =20
The lowest observation = 1
Range of the data = 20-1
= 19(ans)
The range is 19
Step-by-step explanation:
To calculate the range of a set of data, you order the numbers from highest to lowest (ex; 20,20,19,18,16,12,12,10,8,8,7,6,4,4,3,1,1) then you subtract the highest number from the lowest number (ex; 20 - 1)
hope you can understand
it's -4 I just took the test and you will get it write
x^2 y^2(x+y)(x^2 - xy + y^2)
x^2 y^2(x^3 + y^3)
(x+y)(x^2 - xy +y^2)
I only know one way and its x = 7
20 = 5( x -3 )
20/5 = x- 3
4 = x - 3
4 + 3 = x
7 = x
