Answer: The answer is D
Step-by-step explanation: So, we have five parts on it equaling 1, 2, 3, 4 and 5. The top number is our chance, and the bottom number is how many there are in total, so our answer is D, 1/5.
Hope this helps :)

Answer: a = 1.25, b = 2.5, c = 1.25
Step-by-step explanation:
Use vertex form and substitute a point into it (1, 5)
5 = a(1 + 1)^2 + 0
5 = a(2)^2 + 0
5 = 4a
a = 5/4
y = 5/4 (x + 1)^2
y = 5/4 (x^2 + 2x + 1)
1.25 x^2 + 2.5x + 5/4
Is there a "c" value otherwise it's not possible
I’m pretty sure the answer is c
