Edward wants to determine which skateboarder won a race. The actual time taken by four skateboarders to skate the same distance
is shown below: Skateboarder A B C D
Time (in seconds) 4.28 4.24 4.26 4.25
If the stopwatch can measure to the nearest tenth of a second, which skateboarder will show as having a different time from the others?
Skateboarder A
Skateboarder B
Skateboarder C
Skateboarder D
Skateboarder B. 4.24 will show as a different time since the stopwatch rounds to the nearest tenth and to round up it has to be 0.5+ and to round down you need 0.4 or below and in this case Skateboarder B. has a time of 4.24 thus it has a different time than the other times.
A polynomial is an expression that has two or more than terms. These terms are separated by an operation. Only -4/y is not a polynomial. It is a monomial. Monomial is not a polynomial.
