For something to be a function, the input (x value) can only have one output (y value). If an x value has more than one y value, it is not a function.
A.) When x = 1, it has 5 y values. This is not a function
B.) -2 and -1 have two y values. This is not a function
C.) 1 and 2 have two y values. This is not a function
D.) Each input has only one output. This is a function. (Inputs can share the same outputs)
Your answer is D
The apothem of a square is equal to half its side length. Therefore, the square has a side length of 5. The area of a square equals the s^2. Therefore, the area of the square is 5^2=25. (B)
Answer:
4/11
Step-by-step explanation:
Outcomes that meet your requirement are
(1, 6), (2, 6), (6, 1), (6, 2)
for a total of 4 favorable outcomes.
There are 11 outcomes in which one die shows a 6.
So your probability would be 4/11.
