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)
$79
The slope of this line is -2
2x - 5y =9
-5y = -2x + 9 (Subtract 2x from each side)
y= -2x + 14 (add 5 to each side)
-2 is the slope
