An interval scale has measurements where the difference between values is meaningful. For example, the year 0 doesn’t imply that time didn’t exist. And similarly, a temperature of zero doesn’t mean that temperature doesn’t exist at that point. Arbitrary zeros (and the inability to calculate ratios because of it) are one reason why the ratio scale — which does have meaningful zeros — is sometimes preferred.
Answer: x + 30 + 90= 180(sum of angles on a straight line)
x= 180-120
x=60
Answer:
t = 1/2 hour
Step-by-step explanation:
20480 = 80
20480 = 80
20480/80 =
256 =
x = 4
doubling period
2 = 
t = 1/2 hour
does this question have a diagram?if so then plz present it
Answer:
The volume of a cube with side length 2 is 8.
Step-by-step explanation:
The argument of the function is the side length. In v(2), the argument is 2, so the side length of the cube of interest is 2 units.
The value of the function is the volume of the cube. The value of v(2) is 8, so that is the volume of the cube whose side length is 2.
