Step-by-step explanation:
Because the parabola intercepts the x-axis only once, we conclude that the discriminant is 0.
<h3>
What can we say about the discriminant?</h3>
For a quadratic equation:
y = a*x^2 + b*x + c
The discriminant is:
D = b^2 - 4ac
- If D = 0, there is only one real zero.
- If D > 0, there are two real zeros.
- If D < 0, there are two complex zeros.
In the graph we can see that the parabola intercepts the x-axis in its vertex, then the parabola has only one real zero, then we conclude that the discriminant is equal to zero.

Step-by-step explanation:m
The answer is B: The distribution for town A is symmetric, but the distribution of town B is positively skewed.
The answer would be 1/3
as in C O O K I E there are two O's out of 6 letters, so:
2/6 and this is simplified to 1/3
